[AK5536] AK5536 6-Channel Differential 32-bit  ADC 1. General Description The AK553x series is a 32-bit, 768 kHz sampling, differential input A/D converter for digital audio systems. It achieves 111 dB dynamic range and 103 dB S/(N+D) while maintaining low power consumption performance. The AK5536 integrates a 6-channel A/D converter, suitable for mixers and multi-channel recorders. Four types of digital filters are integrated and selectable according to the sound quality preference. The AK5536 can be easily connected to a DSP by supporting TDM audio formats. Additionally, it supports DSD output up to 11.2MHz. The channel summation improves the dynamic range to 114 dB in 6-to-3 mode, to 117 dB in 4-to-1 mode and to 118 dB in 6-to-1 mode. 2.

Normally, this voltage is generated by the internal LDO from TVDD (3.3 V) for digital interface. The internal LDO will be powered up by setting the LDOE pin = “H”. Set the LDOE pin to “L” and supply a 1.8 V power to the VDD18 pin externally when a 1.8 V is used as TVDD. ■ Output Mode The AK5536 is able to output either PCM or DSD data. The DP pin or DP bit select the output mode. Set the PW2 pin = PW1 pin = PW0 pin = “L” or RSTN bit = “0” or PW8-1 bits = “0H” to reset all channels when changing the PCM/DSD mode. The AK5536 outputs data from the SDTO1-3 pins by BICK and LRCK in PCM mode. DSD data are output from the DSDOL1-3 pins and DSDOR1-3 pins by DCLK in DSD mode. DP pin DP bit Interface L 0 PCM H 1 DSD Table 1 PCM/DSD Mode Control ■ Master Mode and Slave Mode The AK5536 requires a master clock (MCLK), an audio serial data clock (BICK) and an output channel clock (LRCK) in PCM mode. In this case, the LRCK frequency will be the sampling frequency. Both master and slave modes are available in PCM mode. In master mode, the AK5536 internally generates BICK and LRCK clocks from MCLK inputs and outputs them from the BICK pin and the LRCK pin. In slave mode, AK5536 operates in the input MCLK, BICK and LRCK. MCLK must be synchronized with BICK and LRCK but the phase is not important. The AK5536 is in master mode when the MSN pin = “H” and in slave mode when the MSN pin = “L”. The AK5536 requires a master clock (MCLK) in DSD mode. Slave mode is not available in DSD mode, only master mode is supported. ■ System Clock [1] PCM Mode The external system clocks, which are required to operate the AK5536, are MCLK, BICK and LRCK in PCM mode. MCLK frequency is determined based on LRCK frequency, according to the operation mode. Table 2, Table 3, Table 4 show MCLK frequencies correspond to the normal audio rate. Set the frequency ratio between Sampling frequency and MCLK by the CKS3-0 pins (Table 5) All channels must be reset when changing the clock mode or audio interface format by the CKS2-0 pins (bits), TDM1-0 pins (bits), DIF1-0 pins (bits) and the MSN pin. In parallel control mode, all channels will be reset by the PDN pin = “L” or PW2-0 pins = “LLL”. In serial control mode, all channels will be reset by RSTN bit = “0” or PW6-1 bits = “0H”. A stable clock must be supplied after releasing the reset. The AK5536 integrates a phase detection circuit for LRCK. If the internal timing becomes out of synchronization in slave mode, the AK5536 is reset automatically and the phase is resynchronized. The following sequence must be executed when synchronizing multiple AK5536’s. Stop all AK5536’s in reset status by setting the PDN pin = “L” → “H” after stopping the system clock. Make pin or register settings while all channels are in reset status. After that, input the same system clock to all AK5536’s. 015099885-E-00 2016/03 - 31 - [AK5536] 32fs 48fs 64fs 96fs 128fs MCLK 192fs 32 kHz N/A N/A N/A N/A N/A N/A 48 kHz N/A N/A N/A N/A N/A N/A 96 kHz N/A N/A N/A N/A N/A N/A 192 kHz N/A N/A N/A N/A 384 kHz N/A N/A fs 768 kHz 24.576 36.864 MHz MHz 24.576 36.864 MHz MHz N/A N/A 24.576 36.864 MHz MHz 256fs 384fs 512fs 768fs 1024fs 8.192 12.288 16.384 24.576 32.768 MHz MHz MHz MHz MHz 12.288 18.432 24.576 36.864 N/A MHz MHz MHz MHz 24.576 36.864 N/A N/A N/A MHz MHz N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A N/A (N/A: Not Available) Table 2.

The AK5536 generates DCLK from MCLK inputs and DSD data outputs (DSDOL1-3 and DSDOR1-3) are synchronized with DCLK. The necessary MCLK frequencies are 512fs and 768fs (fs=32 kHz, 44.1 kHz, 48 kHz). MCLK frequency can be changed by the DCKS pin (bit). After exiting reset (PDN pin = “L” → “H”) upon power-up, the AK5536 is in power-down state until MCLK is input.

DSD Sampling Frequency Select (default) ■ Audio Interface Format TDM1-0 pins(bits), DIF1-0 pins(bits), SLOW pin(bit) and SD pin(bit) settings should be changed when all channel are reset condition. [1] PCM Mode 48 types of audio interface format can be selected by the TDM1-0 pins (bits), MSN pin and DIF1-0 pins (bits) (Table 8, Table 9). In all formats the serial data is MSB-first, 2's complement format. In master mode, the SDTO1-3 is clocked out on the falling edge of BICK. Normal output in slave mode, the SDTO1-3 is clocked out on the falling edge of BICK if 8 kHz ≤ fs ≤ 216 kHz. In other conditions, the data is clocked out on the prior rising edge of BICK to compensate for some delay that renders the edge of data transition near BICK falling edge. Audio interface format is distinguished in four types: Normal mode, TDM128 mode, TDM256 mode and TDM512 mode are available. The TDM1-0 pins (bits) select these modes. In Normal mode (non TDM), AIN1 and AIN2 A/D converted data is output from the SDTO1 pin, AIN3 and AIN4 A/D converted data is output from the SDTO2 pin, AIN5 and AIN6 A/D converted data is output from the SDTO3 pin. The BICK frequency must be in the rage from 48fs to 128fs (fs= 48 kHz) in slave mode if the audio interface format is in normal output (non TDM) and the interface speed is in Normal, Double or Quad mode. Bit length of A/D data is 24-bit or 32-bit and it is selected by the DIF1 pin (bit). The BICK frequency must be set to 32fs, 48fs or 64fs in slave mode if the audio interface format is normal output (non TDM) and the interface speed is in OCT mode. Bit length of A/D data is determined by BICK frequency regardless of the DIF1 pin (bit) if the BICK frequency is 32fs or 48fs. It is 16-bit when the BICK frequency is 32fs and 24-bit when the BICK frequency is 48fs. When the BICK frequency is 64fs, A/D data can be selected between 24-bit and 32-bit by the DIF1 pin (bit). The BICK frequency must be set to 32fs or 48fs in slave mode if the audio interface format is normal output (non TDM) and the interface speed is in EXT mode. Bit length of A/D data is determined by BICK frequency regardless of the DIF1 pin (bit). It is 16-bit when the BICK frequency is 32fs and 24-bit when the BICK frequency is 48fs. 015099885-E-00 2016/03 - 34 - [AK5536] The BICK frequency will be 64fs in master mode if the audio interface format is normal output (non TDM) and the interface speed is Normal, Double or Quad mode. Data bit length can be selected from 24-bit and 32-bit by the DIF1 pin (bit). The MCLK frequency must be 64fs or 96fs in master mode if the audio interface format is normal output (non TDM) and the interface speed is OCT mode. The BICK frequency will be 64fs. Data bit length can be selected from 24-bit and 32-bit by the DIF1 pin (bit). The BICK frequency will be synchronized with the MCLK frequency in master mode if the audio interface format is normal output (non TDM) and the interface speed is HEX mode. The MCLK frequency must be 32fs, 48fs or 64fs. The bit length of A/D data is 16-bit when the MCLK frequency is 32fs, 24-bit when the MCLK frequency is 48fs and 24-bit or 32-bit can be selected by the DIF1 pin (bit) when the MCLK frequency is 64fs. The DIF0 pin selects the A/D data format between MSB justified and I2S Compatible.

Audio Interface Format (TDM Mode) 015099885-E-00 2016/03 - 36 - [AK5536] Cascade Connection in TDM Mode The AK5536 supports cascade connection in TDM mode. All A/D converted data of connected AK5536 are output from the SDTO1 pin of the last AK5536 by cascade connection. When the ODP pin = “L”, a cascade connection of two devices in TDM512 mode is supported. Figure 29 shows a connection example. When the ODP pin = “H”, a cascade connection of two up to sixteen devices is available. When using multiple devices in slave mode on cascade connection, internal operation timing of each device may differ for one MCLK cycle depending on MCLK and BICK input timings. To prevent this timing difference, BICK “↓” should be more than ± 10ns from MCLK “↑” as shown in Table 10. To realize this timing, BICK divided by two should be input on a falling edge of MCLK as shown in Figure 54 when MCLK=2xBICK (normal speed 1024fs mode). When MCLK=BICK (normal speed 512fs mode), MCLK and BICK should be input in-phase as shown in Figure 55 to satisfy the timing shown in Table 10. 256fs, 512fs or 1024fs AK5536 #1 MCLK 48kHz LRCK 512fs BICK 256fs, 512fs or 1024fs TDMIN 48kHz SDTO1 GND 512fs Slave mode BICK BICK SDTO1 GND AK5536 #2 TDMIN LRCK TDMIN LRCK Master mode AK5536 #2 MCLK AK5536 #1 MCLK MCLK 16ch TDM LRCK BICK SDTO1 TDMIN 16ch TDM SDTO1 Slave mode Slave mode TDM512 TDM512 Figure 29.

It does not support Phase Modulation mode when the DCLK frequency is 256fs. DCKB bit controls DCLK polarity.

DSD Mode Timing 015099885-E-00 2016/03 - 45 - [AK5536] ■ Channel Summation (PCM Mode, DSD Mode) Channel Summation function improves the dynamic range and S/N performance by averaging all A/D data of multiple-channel that the same signal is input. The AK5536 supports 6-to-3 mode, 4-to-1 mode, 6-to-1 mode. 6-to-3 mode (1.5-Stereo mode) Improve the dynamic range and S/N for 3 dB (2.5 dB in DSD mode) by averaging two channels. 4-to-1 mode (2-Mono mode) Improve the dynamic range and S/N for 6 dB (5 dB in DSD mode) by averaging four channels. In this mode, the data of other two channels are also averaged and output. 6-to-1 mode (Mono mode) Improve the dynamic range and S/N for 7 dB (6 dB in DSD mode) by averaging six channels. Not-Summation mode (3-Stereo mode) Normal mode that does not execute Summation is called as Not-Summation mode or 3-Stereo mode. Refer to the section “CH Power Down & Channel Summation mode” for details. ■ Optimal Data Placement (PCM Mode, DSD Mode) Assigned data to the SDTO1-3 slot is controlled by the ODP pin setting in parallel control mode. When the ODP pin = “L”, the data is output by Fixed Data Placement mode. Channel assignment of data slot is fixed regardless of enable/disenable of channel summation. For example, averaging data of two channels are output to both channel slots. When the ODP pin = “H”, the data is output by Optimal Data Placement mode that is uses data slot more efficiently. In Optimal Data Placement mode, there are no data redundant of channel summation, and the data is output in MSB justified. Therefore, the maximum number of connecting device in cascade connection will be increased. If the AK5536 is set to 6-to-3 mode (1.5-Stereo Mode), two devices can be connected in TDM256 mode, four devices can be connected in TDM512 mode. If the AK5536 is set to 4-to-1 mode (2-Mono Mode), two devices can be connected in TDM128 mode, four devices can be connected in TDM256 mode and eight devices can be connected in TDM512 mode. If the AK5536 is set to 6-to-1 mode (Mono Mode), four devices can be connected in TDM128 mode, eight devices can be connected in TDM256 mode and sixteen devices can be connected in TDM512 mode. In serial control mode, the data output is Optimal Data Placement mode regardless of the ODP pin setting. Refer to “CH Power Down & Channel Summation mode” for details. 015099885-E-00 2016/03 - 46 - [AK5536] ■ CH Power Down & Channel Summation Setting (PCM Mode, DSD Mode) [1] Parallel Control Mode The setting of the PW2-0 pins and the ODP pin controls the channel power-down and channel summation mode setting in parallel mode (Table 11-Table 16). The PDN pin must be set to “L” when changing the ODP pin and the PW2-0 pins. The power consumption of the device can be improved by setting unused channels to power-down state. In this case, the channel circuit that is powered down will be reset. When the ODP pin = “L”, the PW2-0 pins control channel power-down and 6-to-3 mode. In this mode, AIN1 and AIN2 channel data are summed digitally and output from the SDTO1 (DSDOL1 and DSDOR1) by dividing into half amplitude. In the same manner, AIN3 and AIN4 channel data are summed digitally and output from the SDTO2 (DSDOL2 and DSDOR2) by dividing into half amplitude. AIN5 and AIN6 channel data are summed digitally and output from the SDTO3 (DSDOL3 and DSDOR3) by dividing into half amplitude.

The PW2-0 pins control power down, 6-to-3 mode, 4-to-1 mode and 6-to-1 mode. In 6-to-3 mode, AIN1 and AIN2 channel data are summed digitally and output from the SDTO1 (DSDOL1) of the slot1 by dividing into half amplitude. In the same manner, AIN3 and AIN4 channel data are summed digitally and output from the SDTO1 (DSDOR1) of the slot2 by dividing into half amplitude. AIN5 and AIN6 channel data are summed digitally and output from the SDTO2 (DSDOL2) of the slot3 by dividing into half amplitude. In 4-to-1 mode, AIN1 - AIN4 channel data are summed digitally and output from the SDTO1 (DSDOL1) of the slot1 by dividing into quarter amplitude. AIN5 – AIN6 channel data are summed digitally and output from the SDTO1 (DSDOR1) of the slot2 by dividing into half amplitude. In 6-to-1 mode, AIN1 – AIN6 channel data are summed digitally and output from the SDTO1 (DSDOL1) of the slot1 by dividing into 1/6 amplitude. 015099885-E-00 2016/03 - 47 - [AK5536] Power ON/OFF PW2 PW1 PW0 pin pin pin Ch6 Ch5 Ch4 Ch3 Ch2 Ch1 L L L OFF OFF OFF OFF OFF OFF L L H ON ON ON ON ON ON L H L ON ON ON ON ON ON L H H ON ON ON ON ON ON H L L ON ON ON ON ON ON H L H ON ON ON ON ON ON H H L ON ON ON ON ON ON H H H ON ON ON ON ON ON Table 13.

The filter setting is not available in OCT speed mode, HEX speed mode and DSD mode. So the setting of the digital filter is ignored. SD pin (bit) L (0) L (0) H (1) H (1) SLOW pin (bit) Filter L (0) Sharp Roll-off Filter H (1) Slow Roll-off Filter L (0) Short Delay Sharp Roll-off Filter H (1) Short Delay Slow Roll-off Filter Table 20. Digital Filter Setting ■ Digital HPF (PCM Mode) The AK5536 has a digital high-pass filter for DC offset (include internal offset) cancelation. The digital high-pass filter is enabled by setting the HPFE pin (bit) = “H (1)”. The cut-off frequency of the high-pass filter is fixed 1.0 Hz when fs= 48 kHz (Normal Speed mode), 96 kHz (Double Speed mode) or 192 kHz (Quad Speed mode). The high-pass filter is not available in OCT speed mode, HEX speed mode and DSD mode. So that the setting of the HPFE pin is ignored. The high pass-filter setting should be changed when all channels are reset condition. ■ Overflow Detection (PCM Mode, DSD Mode) [1] PCM Mode The AK5536 has an overflow detect function for the analog input. The OVF pin outputs “H” if one of AIN1 - 6 channels overflows (more than 0.3 dBFS). The OVF pin returns to “L” when analog input overflows are resolved. The OVF output for overflowed analog input has the same group delay as the ADC. [2] DSD Mode Overflow Detection (Error Detection Function) The OVF pin outputs “H” if any channel’s DSD modulators overflows. The OVF pin returns to “L” when overflows are resolved. 015099885-E-00 2016/03 - 52 - [AK5536] ■ LDO The voltage range of TVDD is from 1.7 V to 1.98 V or from 3.0 V to 3.6 V. Set ON/OFF of the LDO by the LDOE pin according to TVDD voltage (Table 21). The internal LDO is switched ON/OFF depending on TVDD voltage range. Additional Voltage Range LDOE PDN LDO VDD18 pin to TVDD pin L L OFF External Power Input 1.7-1.98 V 1.7-1.98 V L H OFF External Power Input 1.7-1.98 V 1.7-1.98 V H L OFF 3.0-3.6 V Pulled Down by 500  internally H H ON LDO Voltage Output 3.0-3.6 V Table 21. LDO Control [1] TVDD=1.7-1.98 V, LDO is OFF (LDOE pin = “L”) The internal LDO does not work properly when the TVDD voltage range is from 1.7 V to 1.98 V. Set the LDOE pin to “L” to switch OFF the LDO. A 1.7 V - 1.98 V is supplied from the VDD18 pin for internal logic circuits. The voltage difference between TVDD and VDD18 must be ±0.1 V or less. [2] TVDD=3.0-3.6 V, LDO is ON (LDOE pin = “H”) The internal LDO should be ON when the TVDD voltage range is from 3.0 V to 3.6 V. It will be the power supply for the internal logic circuit. The VDD18 pin will be a connection terminal for a stabilization capacitor. It is not possible to supply the power to external circuits from the VDD18 pin. ■ Reset The AK5536 must be reset upon power up or when changing the clock setting or clock frequency. It can be reset by the PDN pin or PW2-0 pins and RSTN bit or PW6-1 bits. 015099885-E-00 2016/03 - 53 - [AK5536] ■ Power Up/Down Sequence The AK5536 enters power-down mode by setting the PDN pin to “L”. Digital filters are reset at the same time. [1] PCM Mode In slave mode, internal power down signal (Internal PDN) is released by inputting MCLK, BICK and LRCK after setting the PDN pin to “H”. In master mode, The Internal PDN is released by inputting MCLK after setting the PDN pin to “H”. Initialization cycle starts when the Internal PDN is released. The output data of SDTO will be valid in 583 x 1/fs after exiting power-down mode in slave mode, it will be valid in 578 x 1/fs after exiting power-down mode in master mode. During initialization, the ADC digital outputs of both channels are in 2’s complement format and forced to “0”. The ADC outputs settle to data correspondent to the input signals after the end of initialization. This settling takes approximately the group delay time.

Power-Up/Down Sequence Example Notes (1) The PDN pin should be held to “L” for more than 150 ns after AVDD and TVDD are powered up. (2) a. LDOE pin = “H”, I2C pin = “H” and PSN pin = “H” (Parallel Mode): The internal LDO is powered up by releasing PDN pin to “H”. The Internal PDN is released by toggling MCLK for 16384times. b. LDOE pin = “H” and PSN pin = “L” (Register Mode): The internal LDO is powered up by releasing PDN pin to “H”. The internal PDN is released by toggling internal oscillator clock for 16384 times (max. 10 ms). c. LDOE pin = “L”: The internal PDN is released in 1 ms (max.) after releasing PDN pin to “H”. During this period, digital output and digital in/output pins may output an instantaneous pulse (max. 1 us). Therefore, referring the output of digital pins and data transmission with a device on the same 3-wire serial/I2C bus as the AK5536 should be avoided in this period to prevent system errors. (3) Initialization cycle is 583/fs in slave mode and 578/fs in master mode. (4) The ADC output data is “0” during initialization cycle and power-down mode. (5) The digital output corresponding to analog input has group delay (GD). 015099885-E-00 2016/03 - 54 - [AK5536] Internal PDN Release Sequence Figure 60.

DSD Operation Timing Notes: (1) The internal LDO is powered up by releasing PDN pin to “H”. The internal PDN is released by toggling internal oscillator clock for 16384 times (max. 10ms). The internal PDN is released in max. 1 ms after releasing PDN pin to “H”. Register writings become available when the internal PDN changes to “1”. During this period, digital output and digital in/output pins may output an instantaneous pulse (max. 1 us). Therefore, referring the output of digital pins and data transmission with a device on the same 3-wire serial/I2C bus as the AK5536 should be avoided in this period to prevent system errors. (2) Initialization operation will be completed in 583/fs. (3) DSD output pins output “L” (-full scale data) during power down and initializing operation. DSD output pins output full scale data during phase modulation mode, a reset sequence and a CH power down status. (4) The OVF pin outputs “H” when an excessive signal is input and overflow is detected at internal modulator. The OVF pin status will change after group delay period from the excessive input. (5) In the case above (4), the DSD output data will not be correct. (6) The OVF pin returns to “L” when the input signal settled to a normal state and overflow status of the internal modulator is resolved. The OVF pin status will change after group delay period from the normal input. 015099885-E-00 2016/03 - 56 - [AK5536] ■ Operation Mode Control Operation modes of the AK5536 are set by pins or registers. In parallel control mode, the operation mode is set by pin and register settings are invalid. Therefor the functions that needs register settings are not available in parallel control mode. For register accessing, 3-wire serial and I2C bus communications are available. This control mode of the AK5536 is selected by the I2C pin and the PSN pin. In serial control mode, register settings are prioritized so that all pin settings except the MSN pin setting are ignored. I2C pin L L H H PSN pin Control mode L 3-wire Serial H 3-wire Serial L I2C Bus H Parallel Table 22. Control Mode ■ Register Control Interface (1) 3-wire Serial Control Mode (I2C pin = “L”) The internal registers may be written through the 3-wire µP interface pins (CSN, CCLK and CDTI). The data on this interface consists of a 2-bit Chip address, Read/Write (1bit, Fixed to “1”, Write only), Register address (MSB first, 5bits) and Control data (MSB first, 8bits). Address and data are clocked in on the rising edge of CCLK and data is clocked out on the falling edge. For write operations, data is latched after a low-to-high transition of CSN. The clock speed of CCLK is 5MHz (max). The internal registers are initialized by setting the PDN pin = “L”. In serial control mode, an internal timing circuit is reset by setting RSTN bit = “0” but register values are not initialized.

Control I/F Timing * The AK5536 does not support read commands in 3-wire serial control mode. * When the AK5536 is in power down mode (PDN pin = “L”), a writing into the control registers is prohibited. * The control data cannot be written when the CCLK rising edge is 15 times or less, or 17 times or more during CSN is “L”. 015099885-E-00 2016/03 - 57 - [AK5536] (2) I2C-bus Control Mode (I2C pin = “H” and PSN pin = “L”) The AK5536 supports the fast-mode I2C-bus (max: 400 kHz, Ver1.0). (2)-1. WRITE Operations Figure 63 shows the data transfer sequence of the I2C-bus control mode. All commands are preceded by a START condition. A HIGH to LOW transition on the SDA line while SCL is HIGH indicates a START condition (Figure 69). After the START condition, a slave address is sent. This address is 7 bits long followed by the eighth bit that is a data direction bit (R/W). The most significant five bits of the slave address are fixed as “00100”. The next bits are CAD1-0 (device address bits). This bits identifies the specific device on the bus. The hard-wired input pins (CAD1-0 pins) set these device address bit (Figure 64). If the slave address matches that of the AK5536, the AK5536 generates an acknowledge and the operation is executed. The master must generate the acknowledge-related clock pulse and release the SDA line (HIGH) during the acknowledge clock pulse (Figure 70). R/W bit = “1” indicates that the read operation is to be executed. “0” indicates that the write operation is to be executed. The second byte consists of the control register address of the AK5536. The format is MSB first, and those most significant 3-bits are fixed to zeros (Figure 65). The data after the second byte contains control data. The format is MSB first, 8bits (Figure 66). The AK5536 generates an acknowledge after each byte is received. Data transfer is always terminated by a STOP condition generated by the master. A LOW to HIGH transition on the SDA line while SCL is HIGH defines STOP condition (Figure 69). The AK5536 can perform more than one byte write operation per sequence. After receipt of the third byte the AK5536 generates an acknowledge and awaits the next data. The master can transmit more than one byte instead of terminating the write cycle after the first data byte is transferred. After receiving each data packet the internal 6-bit address counter is incremented by one, and the next data is automatically taken into the next address. If the address exceeds “07H” prior to generating a stop condition, the address counter will “roll over” to “00H” and the previous data will be overwritten. The data on the SDA line must remain stable during the HIGH period of the clock. The HIGH or LOW state of the data line can only change when the clock signal on the SCL line is LOW (Figure 71) except for the START and STOP conditions.

READ Operations Set the R/W bit = “1” for the READ operation of the AK5536. After transmission of data, the master can read the next address’s data by generating an acknowledge instead of terminating the write cycle after the receipt of the first data word. After receiving each data packet the internal 6-bit address counter is incremented by one, and the next data is automatically taken into the next address. If the address exceeds “07H” prior to generating stop condition, the address counter will “roll over” to “00H” and the data of “00H” will be read out. The AK5536 supports two basic read operations: Current Address Read and Random Address Read. (2)-2-1. Current Address Read The AK5536 contains an internal address counter that maintains the address of the last word accessed, incremented by one. Therefore, if the last access (either a read or write) was to address “n”, the next CURRENT READ operation would access data from the address “n+1”. After receipt of the slave address with R/W bit “1”, the AK5536 generates an acknowledge, transmits 1-byte of data to the address set by the internal address counter and increments the internal address counter by 1. If the master does not generate an acknowledge but generates a stop condition instead, the AK5536 ceases transmission.

Random Address Read The random read operation allows the master to access any memory location at random. Prior to issuing a slave address with the R/W bit =“1”, the master must execute a “dummy” write operation first. The master issues a start request, a slave address (R/W bit = “0”) and then the register address to read. After the register address is acknowledged, the master immediately reissues the start request and the slave address with the R/W bit =“1”. The AK5536 then generates an acknowledge, 1 byte of data and increments the internal address counter by 1. If the master does not generate an acknowledge but generates a stop condition instead, the AK5536 ceases transmission.

Grounding and Power Supply Decoupling The AK5536 requires careful attention to power supply and grounding arrangements. Normally AVDD1/2 and TVDD are supplied from analog supply of the system. The power-up sequence between AVDD1/2 and TVDD are not critical when AVDD1/2 and TVDD are supplied separately. DVSS and AVSS1/2 must be connected to the same analog ground plane. System analog ground and digital ground should be wired separately and connected together as close as possible to where the supplies are brought onto the printed circuit board. Decoupling capacitors for high frequency should be placed as near as possible to the supply pin. 2. Reference Voltage The differential voltage between the VREFH1-3 pins and the VREFL1-3 pins are the common voltage of A/D conversion. The VREFL1-3 pins are normally connected to AVSS. In order to remove a high frequency noise, connect a 20 Ω resistor between the VREFH1-3 pins and analog 3.3 V supply, and connect a 0.1 μF ceramic capacitor in parallel with an 100 μF electrolytic capacitor between the VREFH1-3 pins and the VREFL1-3 pins. Especially the ceramic capacitor should be connected as close as possible to the pin. All digital signals, especially clocks, should be kept away from the VREFH1-3 pins and VREFL1-3 pins in order to avoid unwanted noise coupling into the AK5536. 3. Analog Inputs The Analog input signal is differentially supplied into the modulator via the AINn+ and the AINn- pins (n= 1-6). The input voltage is the difference between the ALINn+ and ALINn- pins (n= 1-6). The full scale signal on each pin is nominally 1.85 V (typ). A voltage from AVSS1/2 to AVDD1/2 can be input to the AK5536. The output code format is two’s complement. The internal HPF removes DC offset (including DC offset by the ADC itself). The AK5536 requires a +3.3 V analog supply voltage. Any voltage which exceeds the upper limit of AVDD1/2+0.3 V and lower limit of AVSS1/20.3 V and any current beyond 10 mA for the analog input pins should be avoided. Excessive currents to the input pins may damage the device. Hence input pins must be protected from signals at or beyond these limits. Use caution especially when using ±15 V for other analog circuits in the system. 015099885-E-00 2016/03 - 65 - [AK5536] 4. External Analog Circuit Examples Figure 73 shows an input buffer circuit example 1. (1st order HPF; fc= 0.70 Hz, 2nd order LPF; fc= 351 kHz, gain= 14.5 dB). The analog signal is able to input through XLR or BNC connectors. (short JP1 and JP2 for BNC input, open JP1 and JP2 for XLR input). The input level of this circuit is 9.85 Vpp (AK5536: 1.85 Vpp Typ.). When using this circuit, analog characteristics at fs= 48 kHz is DR= 111 dB, S/(N+D)= 103 dB. The S/(N+D) characteristics of the AK5536 varies depending on DC bias current of the input signal. Set the DC bias voltage in a range from 0.48 x AVDD to 0.52 x AVDD for a better characteristic. * Film capacitors are recommended for the components shown as 15 nF and 1 nF in the figure below. 4.7k 4.7k Analog In 620 JP1 VP+ Vin- 68µ + 9.85Vpp Bias VP- 1n * 3.3k 10 + 1.85Vpp AK5536 AINn+ 100p NJM5534 NJM5534 XLR 15n * VA+ 620 10k Bias 10k JP2 68µ - + 10µ 1n * 3.3k Vin+ 0.1µ 10 + NJM5534 Bias VA=+3.3V VP=15V AK5536 AINn100p 1.85Vpp Figure 73.
