The ADC BCLK and LRCLK ports are flipped between slave and master (input and output) by tying SDA/COUT (Pin 24) to low or high. This is accomplished by moving the J5 jumper to either 0 or SDA/1 (see Figure 2 and Figure 3 for the correct settings). 1. 2. 3. 4. 5. 08421-002 1 ADDR1 CLATCH 0 J8 CCLK ADDR0 0 SCL 1 J7 CIN 0 COUT 0 J6 SDA/1 J5 installation.

You can now open the Automated Register Window Builder application and load the .xml file for the part on the evaluation board. POWERING THE BOARD The AD1938 evaluation board requires a power supply input of ±12 V dc and ground to the three binding posts; +12 V draws ~250 mA, and −12 V draws ~100mA. The on-board regulators provide two 3.3 V rails, one each for AVDD and DVDD for the AD1938. DVDD also supplies power for the active peripheral components on the board. Jumpers are provided to allow access to the power connections of the AD1938. These are convenient points to insert a current measuring device. The only components on the AD1938 side of the jumper are the part itself and the local power supply decoupling. The jumper blocks on the evaluation board are shown in Figure 5.

R160 JP22 R167 MCLKO BUS R166 The evaluation board has a series of jumpers that give the user great flexibility in the MCLK clock source for the AD1938. MCLK can come from six different sources: passive crystal, active oscillator, external clock in, S/PDIF receiver, and two header connections. Note that the complex programmable logic device (CPLD) on the board must have a valid clock source; the frequency is not critical. These jumper blocks can assign the CPLD clock as well. Most applications of the board use MCLK from either the S/PDIF receiver or one of the header (HDR) inputs. Figure 6 to Figure 9 show the on-board active oscillator disabled so that it does not interfere with the selected clock. The clock feed to the CPLD comes directly from the clock source.

GND, CM, and FILTR can be selected as a reference; it is advisable to shut down the power to the board before changing this switch. The CM and FILTR lines are very sensitive and do not react well to a change in load while the AD1938 is active. A series of jumpers allows the user to dccouple the buffer circuit to the ADC analog port when CM and FILTR are selected (see Figure 14).

VREF Selection and DC Coupling Jumpers There are two types of digital interfacing, S/PDIF and discrete serial. The input and output S/PDIF ports have optical and coaxial connectors. The serial audio connectors use 1 × 2 100 mil spaced headers with pins for both signal and ground. The LRCLK, BCLK, and SDATA paths are available for both the ADC and DAC on the HDR1 and HDR2 connectors. Each has a connection for MCLK; each HDR MCLK interface has a switch to set the port as an input or output, depending on the master or slave state of the AD1938. Figure 12.

LRCLK Loop Filter Selected Clock and Control Normally, the MCLK filter is the default selection; it is also possible to use the register control window to program the PLL to run from the LRCLK. In this case, the jumper must be changed as shown in Figure 13. CONNECTING AUDIO CABLES Analog Audio The analog inputs and outputs use 3.5 mm TRS jacks; they are configured in the standard configuration: tip = left, ring = right, sleeve = ground. The analog inputs to IN1 and IN2 generate 0 dBFS from a 1 V rms analog signal. The on-board buffer circuit creates the differential signal to drive the ADC with 2 V rms at the maximum level. The DAC puts out a 0.8775 V rms singleended signal at 0 dBFS; this signal is buffered and filtered before the OUT connectors. There are test points that allow direct access to the ADC and DAC pins; note that the ADC and DAC have a common-mode voltage of 1.5 V dc. These test points require proper care so that improper loading does not drag down the common-mode voltage, and the headroom and performance of the part do not suffer. The AD1938 is designed to run in standalone mode at a sample rate (fS) of 48 kHz, with an MCLK of 12.288 MHz (256 × fS). In standalone slave mode, both ADC and DAC ports must receive valid BCLK and LRCLK. The AD1938 can be clocked from either the S/PDIF receiver or the HDR1 connector; the ADC BCLK and LRCK port sources are selected with S2, Position 2 and Position 3. For the S/PDIF master, both switches should be off. For HDR1, S2, Position 3, should be on (see the detail in Figure 15 and Figure 16). The DAC BCLK and LRCK port sources are selected with S2, Position 5 and Position 6. For the S/PDIF master, both switches should be off. For HDR1, S2, Position 6, should be on. Note that HDR2 is not implemented in the CPLD routing code. It is also possible to configure the AD1938 ADC BCLK and LRCK ports to run in standalone master mode; moving J5 to SDA/1, as shown in Figure 3, changes the state of the AD1938. Setting S2, Position 2 and Position 5, to on selects the proper routing to both the S/PDIF receiver and the HDR1 connector. Rev. 0 | Page 5 of 32 UG-045 Evaluation Board User Guide In this mode, the AD1938 ADC port generates BCLK and LRCLK when given a valid MCLK. For full flexibility of the AD1938, the part can be put in SPI control mode and programmed with the Automated Register Window Builder application (see Figure 4 for the appropriate jumper settings). Changing the registers and setting the DIP switches allow many possible configurations. In the various master and slave modes, the AD1938 takes MCLK from a selected source and can be set to generate or receive either BCLK or LRCLK to or from either the ADC or the DAC port, depending on the settings and requirements. As an example, to set the ADC port as master, switch the ADC Control 2 register bits for BCLK and LRCLK to master, and change S2, Position 2 and Position 5, to on. In this mode, the board is configured so that the ADC BCLK and LRCLK pins are the clock source for both the ADC destination and the DAC data source. For the DAC port to be the master, the DAC Control 1 register bits for BCLK and LRCLK must be changed to master, and S2, Position 2 and Position 3, and S2, Position 5 and Position 6, must all be on. On this evaluation board, these settings allow the master port on the AD1938 to drive both the S/PDIF and the HDR connections. Many combinations of master and slave are possible (see Figure 15 and Figure 16 for the correct settings). S/PDIF Audio The settings shown in Figure 15 and Figure 16 show the details of clock routing and control for both the ADC and DAC ports. The board is shipped with the S/PDIF port selected as the default; the hex switches are set to 0, and all DIP switches are set to off. The AD1938 is shipped in standalone mode (see Figure 2); the BCLK and LRCLK signals run from the S/PDIF receiver to the ADC and DAC ports of the AD1938. In this default configuration, the DAC audio path routes the S/PDIF audio signal to all four stereo AD1938 DSDATA inputs simultaneously. The rotary switch, S4, allows the user to select individual stereo pairs for transmission of the analog signal. Position 0 is the default; Position 1 through Position 4 allow the S/PDIF input signal to be assigned to Pair 1 to Pair 4, respectively. Also in this default configuration, the IN1 analog is routed through the AD1938 ADC ASDATA1 path to the S/PDIF output. IN2 is selected by changing the S3 DIP switch, Position 8, from 0 to 1. HDR Connectors—Serial Audio Routing of serial audio to and from the HDR1 connector is controlled by DIP S3, Position 6 and Position 7, and Rotary S4. For the DAC audio signal path, S4, Position 8, assigns the data signal coming into HDR1 DSDATA1 to all four DSDATA ports on the AD1938. S4, Position 9, assigns the HDR1 labeled ports to the associated port on the AD1938. Other Options It is possible to mute all data going to the DSDATA ports of the AD1938 by selecting S4, Position 7. This shows the SNR of the DACs To use other fS rates, the USBi must be connected and the AD1938 registers must be programmed accordingly. For example, adjusting the fS rate to 96 kHz requires that the ADC and DAC Control 0 registers have sample rates set to 96 kHz (see Figure 15 and Figure 16 for the complete list of options). The CPLD code is presented in the CPLD Code section and is included with the evaluation board; alterations and additions to the functionality of the CPLD are possible by altering the code and reprogramming the CPLD.
