ADC1213D125HN

ADC1213D series Dual 12-bit ADC; 65 Msps, 80 Msps, 105 Msps or 125 Msps; serial JESD204A interface Rev. 6 — 9 February 2011 Product data sheet 1. General description The ADC1213D is a dual-channel 12-bit Analog-to-Digital Converter (ADC) optimized for high dynamic performance and low power at sample rates up to 125 Msps. Pipelined architecture and output error correction ensure the ADC1213D is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a 3 V source for analog and a 1.8 V source for the output driver, it embeds two serial outputs. Each lane is differential and complies with the JESD204A standard. An integrated Serial Peripheral Interface (SPI) allows the user to easily configure the ADC. A set of IC configurations is also available via the binary level control pins taken, which are used at power-up. The device also includes a programmable full-scale SPI to allow flexible input voltage range of 1 V to 2 V (peak-to-peak). Excellent dynamic performance is maintained from the baseband to input frequencies of 170 MHz or more, making the ADC1213D ideal for use in communications, imaging, and medical applications. 2.

Optimal performance is achieved using differential inputs with the common-mode input voltage (VI(cm)) on pins INxP and INxM set to 0.5VDDA. The full-scale analog input voltage range is configurable between 1 V (p-p) and 2 V (p-p) via a programmable internal reference (see Section 11.2 and Table 21). Figure 6 shows the equivalent circuit of the sample-and-hold input stage, including ElectroStatic Discharge (ESD) protection and circuit and package parasitics.

Input sampling circuit The sample phase occurs when the internal clock (derived from the clock signal on pin CLKP/CLKM) is HIGH. The voltage is then held on the sampling capacitors. When the clock signal goes LOW, the stage enters the hold phase and the voltage information is transmitted to the ADC core. 11.1.2 Anti-kickback circuitry Anti-kickback circuitry (RC filter in Figure 7) is needed to counteract the effects of a charge injection generated by the sampling capacitance. The RC filter is also used to filter noise from the signal before it reaches the sampling stage. The value of the capacitor should be chosen to maximize noise attenuation without degrading the settling time excessively. R INPA/ INBP C R INAM/ INBM 001aan679 Fig 7. Anti-kickback circuit The component values are determined by the input frequency and should be selected so as not to affect the input bandwidth.

If single-ended is selected, the input pin (CLKM or CLKP) is selected via control bit SE_SEL. If single-ended is implemented without setting bit SE_SEL accordingly, the unused pin should be connected to ground via a capacitor. 11.3.3 Clock input divider The ADC1413D contains an input clock divider that divides the incoming clock by a factor of 2 (when bit CLKDIV2_SEL = logic 1; see Table 20). This feature allows the user to deliver a higher clock frequency with better jitter performance, leading to a better SNR result once acquisition has been performed. 11.3.4 Duty cycle stabilizer The duty cycle stabilizer can improve the overall performance of the ADC by compensating the input clock signal duty cycle. When the duty cycle stabilizer is active (bit DCS_EN = logic 1; see Table 20), the circuit can handle signals with duty cycles of between 30 % and 70 % (typical). When the duty cycle stabilizer is disabled (DCS_EN = logic 0), the input clock signal should have a duty cycle of between 45 % and 55 %.

It provides access to the registers that control the operation of the chip in both read and write modes. This interface is configured as a 3-wire type (SDIO as bidirectional pin). SCLK acts as the serial clock, and CS acts as the serial chip select. Each read/write operation is sequenced by the CS signal and enabled by a LOW level to to drive the chip with 2 bytes to 5 bytes, depending on the content of the instruction byte (see Table 14). Table 14. Bit Description SPI instruction bytes MSB 7 R/W[1] A7 [1] LSB 6 W1 A6 5 W0 A5 4 A12 A4 3 A11 A3 2 A10 A2 1 A9 A1 0 A8 A0 R/W indicates whether a read (logic 1) or write (logic 0) transfer occurs after the instruction byte Table 15. R/W[1] 0 1 [1] Read or Write mode access description Description Write mode operation Read mode operation Bits W1 and W0 indicate the number of bytes transferred after the instruction byte. Table 16. W1 0 0 1 1 Number of bytes to be transferred W0 0 1 0 1 Number of bytes transferred 1 byte 2 bytes 3 bytes 4 or more bytes Bits A12 to A0 indicate the address of the register being accessed. In the case of a multiple byte transfer, this address is the first register to be accessed. An address counter is incremented to access subsequent addresses.

The falling edge on pin CS in combination with a rising edge on pin SCLK determine the start of communications. 2. The first phase is the transfer of the 2-byte instruction. 3. The second phase is the transfer of the data which can vary in length but is always be a multiple of 8 bits. The MSB is always sent first (for instruction and data bytes) 4. A rising edge on pin CS indicates the end of data transmission.

By using the register “Channel index”, the user can choose which ADC channel receives the next SPI-instruction. By default the channel A and B receives the same instructions in write mode. In read mode only A is active. ADC1213D_SER All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.
