Evaluating the ADAU1962/ADAU1966 High Performance,
Low Power, Multibit Sigma-Delta DACs
PACKAGE CONTENTS
On-board regulators derive 9 V, 5 V, and 3.3 V supplies for the
ADAU1962/ADAU1966 and peripherals. The ADAU1962/
ADAU1966 can be controlled through either an I2C or SPI
interface. A small external interface board, EVAL-ADUSB2EBZ,
also called an USBi, connects to a PC USB port and provides
either I2C or SPI access to the evaluation board through a ribbon
cable. A graphical user interface (GUI) program, the Automated
Register Window Builder, is provided for easy programming of
the chip in a Microsoft® Windows® PC environment. The
evaluation board allows demonstration and performance testing
of most ADAU1962/ADAU1966 features, including high
performance digital-to-analog converter (DAC) operation.

EVALUATION BOARD OVERVIEW
This user guide details the design and setup of the evaluation
board for the ADAU1962/ADAU1966. Because the ADAU1962
is a 12-channel device and the ADAU1966 is a 16-channel
device, the DAC 13 through DAC 16 outputs do not function
on the ADAU1962 evaluation board. The evaluation board must
be connected to an external 12 V dc power supply and ground; the
board draws approximately 150 mA.
The board has an S/PDIF receiver with RCA and optical
connectors, as well as a discrete serial audio interface that is
available on the Analog Devices, Inc. system development
platform (SDP) interface. Analog outputs are accessible with two
D-sub, 25-pin connectors using the professional audio standard. A
single D-sub, 25-pin to XLR male cable is included with the board
for connecting individual DAC channels to an audio system.

SETTING UP THE EVALUATION BOARD
STANDALONE MODE
The ADAU1962/ADAU1966 have a standalone mode that allows
the user to choose between a limited number of operation modes
without the need for a control interface. Applying a jumper across
JP21, as shown in Figure 2, pulls SA_MODE (Pin 46) high,
enabling the standalone mode in the ADAU1962/ADAU1966.
The SA_MODE selections are listed in Table 1.

The ADAU1962/ADAU1966 evaluation board arrives configured
for S/PDIF input. The S/PDIF receiver operates as a clock master,
putting out an I2S stream at 256 × fS. For a quick startup, the
ADAU1962/ADAU1966 are in standalone mode with the settings
shown in Figure 2. Pin 42 is pulled high (1) and Pin 43 to Pin 45 are
pulled low (0). According to Table 1, this puts the ADAU1962/
ADAU1966 in slave mode, running at 256 × fS, while common
mode (CM) is set to 2.25 V and the audio serial port is in I2S mode.
Notice in Figure 2 that the jumper for Pin 42 is assigned to 1 and
that the other pins are assigned to 0.
10717-003
On the ADAU1962/ADAU1966 evaluation board, each of the four
ADAU1962/ADAU1966 control port pins is brought to a block of
jumpers, allowing each pin to be assigned to either the I2C port or
the SPI port. In standalone mode, these jumpers can connect the
individual pins to high or low to put the ADAU1962/ADAU1966
in the desired mode.

Figure 3 shows the other options for each SA_MODE configuration
pin; master mode, running at 384 × fS, CM set to 1.50 V, and
the audio serial port in TDM mode. In the case where the
ADAU1962/ADAU1966 are put in TDM mode, Pin 31 and
Pin 32 can be pulled high or low to achieve the modes listed in
Table 1. The correct pins are outlined in the top left corner of
Figure 3, as DSD8 and DSD7.

I2C AND SPI CONTROL
The evaluation board can be configured for live control over
the registers in the ADAU1962/ADAU1966. When the
Automated Register Window Builder software is installed
and the USBi control interface is plugged into the board, the
software can control the ADAU1962/ADAU1966. For this
configuration, the ADAU1962/ADAU1966 must be assigned to
I2C mode using Address 00. See Figure 4 for the correct jumper
positions.

POWERING THE BOARD
The ADAU1962/ADAU1966 evaluation board requires a power
supply input of 12 V dc and ground to the power jack; 12 V
draws ~150 mA at higher sample rates with all channels running.
The on-board regulators provide 9.0 V, 5.0 V, and 3.3 V rails. The
9.0 V rail is derived from 12 V by a linear regulator; it provides
voltage to the audio op amp in the active output filter for
Channel 1 and Channel 2. The 5.0 V rail is derived from 12 V
by a switching regulator; it can supply AVDD as well as IOVDD
for the ADAU1962/ADAU1966 and other peripherals. The 3.3 V
rail is derived from the 5.0 V supply by an LDO linear regulator;
it provides voltage to AVDD and IOVDD as well as other active
peripherals.
Links are provided along each ADAU1962/ADAU1966 power rail
to give access for current measurement (see Figure 8). These
links also allow directly supplying voltage from an outside
source.
10717-008
AVDD and IOVDD are selected on the board using 0 Ω, 0805
package resistors. Install only one resistor for each load, AVDD
and IOVDD, as described in Figure 6. Figure 6 shows AVDD
fed from 5.0 V and IOVDD fed from 3.3 V.
Figure 8. ADAU1962/ADAU1966 Power Links
RESET FOR THE EVALUATION BOARD
10717-006
The ADAU1962/ADAU1966 evaluation board has provision for
resetting and powering down the ADAU1962/ADAU1966. S2 on
the evaluation board, shown in Figure 9, is a momentary reset
switch that pulls the master reset (MR) line low; this line
controls the reset generator U10. MR is also connected to the
USBi and SDP INTF connectors through steering diodes and
protection resistors so that outside devices can control the reset
state of the evaluation board, as shown in Figure 26. The power
down jumper, JP5, allows the MR line to be tied low. The output
of the reset generator drives the PU_/RST line.
Figure 6. AVDD and IOVDD Selection Resistors
The PU_/RST line is directly connected to two devices: the S/PDIF
receiver and the ADAU1962/ADAU1966. A pull-down resistor
holds the line low until the reset generator, U10, asserts the line
high, as shown in Figure 26. The PU_/RST line is also connected
to a pin on the SDP INTF through a steering diode and protection
resistor, allowing external reset control.
10717-009
The ADAU1962/ADAU1966 have an internal voltage regulator
that allows the user to derive DVDD and PLLVDD from the
AVDD voltage source. The external PNP transistor, Q1, and
passives, C36, C40 and R56, make the regulator circuit shown in
Figure 7. Short both JP9 and JP11 to activate the circuit; JP9
supplies the emitter of the PNP, and JP11 powers the VSUPPLY
pin (Pin 25) on the ADAU1962/ADAU1966.

SETTING UP THE MASTER CLOCK (MCLK)
10717-012
The MCLK routing on the evaluation board is handled by a block
of jumpers, J5, allowing any one of four sources to be selected:
SPDIF, SMA connector, active OSC, and INTF connector. The
board comes with SPDIF selected, as shown in Figure 10.
10717-010
Figure 12. INTF Input Enabled and Selected
Figure 10. SPDIF Selected as MCLK Source
To route MCLK from the ADAU1962/ADAU1966 to the SDP
interface, remove the shorting jumper from JP6 (MCLK_SEL); this
changes the direction of the level translators and feeds a buffered
version of the MCLKO signal from the ADAU1962/ADAU1966 to
the EI3_MCLK pin on the SDP interface.
CRYSTAL OPERATION
The evaluation board has a 12.288 MHz active oscillator that
can be selected by shorting the OSC_EN jumper, JP8, and
selecting OSC on J5, as shown in Figure 11.
10717-011
The ADAU1962/ADAU1966 evaluation board is shipped
without R49 on the board, effectively disabling the crystal circuit.
For operation with a crystal, install a 150 Ω, 0402 resistor and
remove any jumpers from J5. For permanent use of the crystal,
remove the 0 Ω resistor, R39.
10717-013
Figure 11. Active OSC-Enabled and Selected as MCLK
When using the SDP interface to add serial audio onto the
evaluation board, MCLK can either be supplied by the SDP
board, or it can be supplied by the MCLKO pin of the
ADAU1962/ADAU1966.
Figure 13. Crystal Circuit Near ADAU1962/ADAU1966
To route MCLK from the SDP interface to the ADAU1962/
ADAU1966, apply a shorting jumper across JP6 (MCLK_SEL),
as shown in Figure 12; this sets the direction of the level
translators on the board to receive an MCLK signal from the
SDP interface, EI3 1A, Pin 119 (EI3_MCLK), as shown in
Figure 28. Next, select INTF on JP5 to route the output of
the MCLK level translator to the MCLKI pin of the
ADAU1962/ADAU1966.

PLL SELECTION
The PLL in the ADAU1962/ADAU1966 is very flexible,
allowing the part to run from a wide range of either MCLK or
LRCLK frequencies. It is also possible to shut the PLL off
altogether and use the part in direct MCLK mode; functionality
with no PLL is limited to 256 × fS.
10717-016
By default, the ADAU1962/ADAU1966 run from the PLL using
MCLK as the clock source. The MCLK loop filter must be
selected using JP2, as shown in Figure 14.
Figure 16. S/PDIF Input Selector Switch, SW1
10717-014
A series of resistors is provided to set the functional mode of the
S/PDIF receiver. By default, the S/PDIF receiver runs in master
mode, 256 × fS, I2S format; consult the data sheet for the S/PDIF
receiver to make changes to the hardware mode.
Figure 14. MCLK Selection for PLL Loop Filter
10717-015
DLRCLK can be selected as the PLL clock source using the PLL
and Clock Control Register 0, Register 0x00, Bits[7:6]. In this
case, the LRCLK loop filter must be selected, as shown in Figure 15.
If DLRCLK is selected as the PLL clock, there is no need for an
MCLK signal.
The jumpers shown in Figure 17 are set for the S/PDIF receiver
to drive the DBCLK and DLRCLK clock ports and the eight
DSDATAx lines of the ADAU1962/ADAU1966. JP22 selects the
input to the buffer; the output of this buffer shows up on the righthand column of JP13 to JP20. The pins in the middle column of
these jumpers are connected to the DSDATAx pins of the
ADAU1962/ADAU1966 through the appropriate line termination.
DBCLK and DLRCLK selections are made with JP10 and JP12,
respectively, where the middle pins are connected to the
DBCLK and DLRCLK pins of the ADAU1962/ADAU1966.
Figure 15. LRCLK Selection for PLL Loop Filter
DIGITAL AUDIO CONNECTIONS AND ROUTING
The ADAU1962/ADAU1966 evaluation board has two separate
inputs for digital audio signals: S/PDIF and SDP interface.
10717-017
The S/PDIF receiver can handle either of two options: COAX
uses the RCA jack, J1, and OPT uses the Toslink jack, U1. The
S/PDIF input is selected using S1, as shown in Figure 16.
Figure 17. S/PDIF Data and Clock Routing
The SDP interface, J6 and J8, make up a standard interconnect
within Analog Devices. They provide for transfer of digital audio,
clocks, and control between boards. For additional information,
see the pinout included in the schematic in Figure 28.
Rev. A | Page 7 of 28
UG-416
Evaluation Board User Guide
Channel 1 and Channel 2 are also available as single-ended outputs
on a stereo, 3.5 mm stereo jack, J14. The J9 and J10 jumpers assign
the differential outputs of the DAC to either the passive differential
output or the active single-ended filter.
Figure 19 shows J9 and J10 set for the passive differential output
available on the D-sub connector.
10717-019
Figure 18 shows the jumpers configuration for using the SDP
interface connector as the digital audio source. JP22 is set so
that the DSDATA1 source from the SDP interface is driving the
buffer, and this buffer is connected to all eight/six DSDATAx
inputs of the ADAU1962/ADAU1966. JP10 and JP12 are set for
the ADAU1962/ADAU1966 to run in slave mode from clocks
supplied by the SDP interface.

USING THE ADAU1962/ADAU1966
When the ADAU1962/ADAU1966 start in standalone mode, it is
operational upon power up.
Figure 18. SDP Interface DSDATA1 Distribution
CONNECTING ANALOG AUDIO CABLES
There are two forms of the analog outputs of the ADAU1962/
ADAU1966 evaluation board: differential outputs and singleended outputs.
The differential outputs appear on through hole test points as well
as on 25-way, female D-sub connectors. The pinout of these D-sub
connectors follows the professional audio standard for eight
differential signals on a single jack. A single 25-pin male D-sub
to XLR male harness has been provided for testing and evaluation
purposes. These cables are widely available on the open market.
The differential outputs of the ADAU1962/ADAU1966 drive
the connectors directly through a simple 1-pole RC filter and
appropriate ac coupling.
If the ADAU1962/ADAU1966 are not powered up in
standalone mode, the USBi must be connected to set the
appropriate registers to make the part operational. First, the
ADAU1962/ADAU1966 must be activated using the PLL and
Clock Control 0 register (Address 0x00) by setting the PUP bit
(Bit 0) to 1 for master power-up. Next, using the DAC Control 0
register (Address 0x06) set the MMUTE bit (Bit 0) to 0 for
normal operation. The ADAU1962/ADAU1966 now pass audio
in its default mode: I2S, 256 × fS, slave mode, and CM = 2.25 V.
If different settings are desired, it is recommended to program
the custom settings before unmuting the part.
