With the control jumpers set to standalone slave mode, all of S2
and S3 set to off, and both mode switches (S4 and S5) set to 0.
The S/PDIF receiver is the LRCLK, BCLK, and SDATA source.
The default MCLK jumper setting routes MCLK from the
S/PDIF receiver to the AD1937/AD1939. With a valid S/PDIF
data stream connected to a selected S/PDIF input port, the
board passes audio from the S/PDIF port to all four stereo
outputs and from Stereo IN1 to the S/PDIF output ports. IN2
can be selected by changing S3, Position 8, to on. Other serial
audio clock and data routing configurations are described in the
Switch and Jumper Settings section.
HARDWARE SETUP—USBi
SPI AND I2C CONTROL
To set up the USBi hardware, follow these steps:
The evaluation board can be configured for interactive control
of the registers in the AD1937/AD1939 by connecting the SPI
or I2C port to the USBi. SPI and I2C jumper settings are shown
in Figure 4 and Figure 5. All part variations are SPI (for the
AD1939). Note that the Automated Register Window Builder
software controls the AD1937 (I2C) only when the ADDR
jumpers are set to 00 and the correct .xml file is loaded.

The AD1937/AD1939 evaluation board requires power supply
input of ±12 V dc and ground to the three binding posts; +12 V
draws ~250 mA, and −12 V draws ~100 mA. The on-board
regulators provide two 3.3 V rails and one 5.0 V rail. The 3.3 V
rails supply AVDD and DVDD for the AD1937/AD1939; DVDD
also supplies power for the peripheral active components on the
board. The 5.0 V rail provides voltage only to the AD1937/
AD1939 internal regulator, which consists of a PNP pass transistor and a few passive components. The PNP is driven into
3.3 V regulation by the VDRIVE pin of the AD1937/AD1939,
with the VSUPPLY and VSENSE pins acting as power and
feedback for the regulator. An appropriate sized PNP can supply
3.3 V to the AVDD and DVDD pins of the AD1937/AD1939.
The jumper blocks are shown in Figure 6 and Figure 7.
The AD1937/AD1939 evaluation board has a series of jumpers
that give the user great flexibility in the MCLK clock source of
the AD1937/AD1939. 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 a clock to the CPLD as well. Most applications
of the board use MCLK from either the S/PDIF receiver or one
of the header (HDR) inputs. Figure 8 to Figure 10 show the onboard 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.

The first step in using the AD1937/AD1939 internal regulator is
to provide power to the regulator circuit by moving the AD1937/
AD1939 REG jumper from DISABLE to ENABLE, as shown in
Figure 7. Three discrete jumpers allow the AD1937/AD1939 to
be run from either the main AVDD and DVDD regulators or
the AD1937/AD1939 internal regulator. These jumpers also
allow measurement of current drawn by the individual sections
of the AD1937/AD1939. The only components on the AD1937/
AD1939 side of the jumper are the AD1937/AD1939 and the
supply decoupling capacitors.

Figure 11. Active On-Board Oscillator as Master; the AD1939 and
CPLD as Slaves
The MCLK configurations shown in Figure 12 and Figure 13
use the AD1937/AD1939 MCLKO port to drive the CPLD and,
possibly, the HDRs. The passive crystal runs the AD1937/AD1939
at 12.288 MHz. Figure 13 shows the MCLKI shut off; this is the
case when the PLL is set to lock to LRCLK instead of to MCLK.
CONFIGURING THE PLL FILTER
The PLL for the AD1937/AD1939 can run from either MCLK
or LRCLK, according to its setting in the PLL and Clock Control 0
register, Bits[6:5]. The matching RC loop filter must be connected to LF (Pin 61) using JP15. See Figure 14 and Figure 15
for the jumper positions.

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 15.
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 1.8 V rms
differential signal; this signal becomes single-ended for 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 ADC buffer circuit is designed with a switch (S1) that
allows the user to change the voltage reference for all of the
amplifiers. 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
AD1937/AD1939 is active. A series of jumpers allows the user
to dc-couple the buffer circuit to the ADC analog port when
CM and FILTR are selected (see Figure 16).
There are two types of digital interfacing, S/PDIF and discrete
serial. The input and output S/PDIF ports have both 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 AD1937/AD1939.
SWITCH AND JUMPER SETTINGS
Clock and Control
The AD1937/AD1939 are 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 AD1937/AD1939
can be clocked from either the S/PDIF receiver or the HDR1
connector; the ADC BCLK and LRCK port sources are selected
with SW2, Position 2 and Position 3. For S/PDIF master, both
switches should be off. For HDR1, SW2, Position 3, should be
on (see the detail in Figure 17 and Figure 18). The DAC BCLK
and LRCK port sources are selected with SW2, Position 5 and
Position 6. For S/PDIF master, both switches should be off. For
HDR1, SW2, Position 6, should be on. Note that HDR2 is not
implemented in the CPLD routing code.
It is also possible to configure the AD1937/AD1939 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 AD1937/AD1939. Setting SW2, Position 2 and Position 5, to
on selects the proper routing to both the S/PDIF receiver and
the HDR1 connector. In this mode, the AD1937/AD1939 ADC
port generates BCLK and LRCLK when given a valid MCLK.

Evaluation Board User Guide
UG-040
For the full flexibility of the AD1937/AD1939, the part can be
put in SPI/I2C control mode and programmed with the
Automated Register Window Builder application (see Figure 4
and Figure 5 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
AD1937/AD1939 take 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 SW2, 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 SW2, Position 2 and Position 3, and SW2, Position 5
and Position 6, must all be on. On this evaluation board, these
settings allow the master port on the AD1937/AD1939 to drive
both the S/PDIF and the HDR connections. Many combinations
of master and slave are possible (see Figure 17 and Figure 18 for
the correct settings).
S/PDIF Audio
The settings in Figure 17 and Figure 18 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 AD1937/AD1939 are shipped in standalone slave mode
(see Figure 2); the BCLK and LRCLK signals run from the S/PDIF
receiver to both ADC and DAC ports of the AD1937/AD1939.
In this default configuration, the DAC audio path routes the
S/PDIF audio signal to all four stereo AD1937/AD1939 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 to Position 4 allow the
S/PDIF input signal to be assigned to Pair 1 to Pair 4, respectively.
Also in this default configuration, IN1 analog is routed through
the AD1937/AD1939 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 SW3, 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 AD1937/AD1939. S4, Position 9, assigns the HDR1
labeled ports to the associated port on the AD1937/AD1939.
Other Options
It is possible to mute all data going to the DSDATA ports of the
AD1937/AD1939 by selecting S4, Position 7. This shows the
SNR of the DACs.
To use other fS rates, the USBi must be connected and the
AD1937/AD1939 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 17 and Figure 18 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.

1) DIP Switch S2 controls the AD193x ADC a nd DAC serial clock source selection. One of four clock sources is selected based on the setting. SPDIF Receiver
CS8416, Header Connector HDR1, ADC serial clocks, or DAC serial clock can be the clock source. ADC a nd DAC serial clock selection is controlled independently.
2) The AD193x master clock source should be selected using the JP28, JP29, JP30, and JP31 header jumpers such that the MCLK source is in sync with the DAC/ADC serial clock and data source.
ADC and DAC Serial Clock (BCLK, LRCLK) Source Selection and Routing (Switch S2)
1) DIP Switch S2 Position-8 (SPDIF_RX_TX reset) must be toggled after power-up for proper operation of the SPDIF receiver and transmitter.
2) The AD193x evalution board defaults the AD193x codec to standalone mode preventing SPI/I2C operation. The J5, J6, J7, and J8 he ader jumpers can be changed for SPI/I2C operation.

Rotary hex Switch S4 selects the AD193x DAC serial data source. The DAC data source can be either SPDIF Receiver CS8416 or can be provided by the Header Connector HDR1. It is important to note that the DAC data source should be in sync with the DAC
serial port clock source (set by DIP Switch S2, Positions [5:6]). DIP Switch S3 routes the ADC serial data among AD193x, SPDIF Transmitter CS8406, and Header Connector HDR1 in stereo, TDM, and aux mode.
