Evaluation Board User Guide 

 

EVALUATION BOARD SETUP INSTRUCTIONS 

To setup the 

EVAL-ADAU1977Z

, the user needs a 5 V power 

supply, differential analog input source, and a PC with a USB 
port. Use a single 5 V, 1 A current rating for the power supply. 
For full evaluation of the 

ADAU1977

, a ±20 V supply is 

required. This power supply facilitates the generation of a 
10 V rms signal as well as a VBAT supply for microphone 
diagnostics.  

JUMPER SETTINGS 

See Figure 2 for the setup of the evaluation board connections. 
Connect the positive power supply lead to J5 and the 0 V lead to 
J4 of the evaluation board. Do not turn the power supply on at 
this time. 
In the power supply section, take the following steps: 
1.

 

Set Jumpers J13 and J14 to the 

INT

 position.  

2.

 

Set Switch S1 to the 

ON

 position.  

3.

 

Set Jumper J10 to the desired IOVDD supply, 3.3 V, or 
1.8  V.  

4.

 

Set Jumper J11 to the 

INT

 position for the internal 

IOVDD. 

5.

 

Set Switch S2 to the 

ON

 position to turn on the 1.8 V 

regulator. 

In the daughter board section, take the following steps: 
1.

 

Install Jumpers J16, J21, J24, and J33. The J16 jumper 
provides the AVDD. Jumpers J21 and J24 provide the 3.3 V 
power supply to the boost converter. The J33 jumper 
provides the IOVDD to the 

ADAU1977

/

ADAU1978

/

ADAU1979

In the PLL and MCLK section, take the following steps: 
1.

 

Select the master clock source. The evaluation board 
provides three options for providing the master clock to 
the ADC. The three options include the following: the on-
board 12.288 MHz oscillator, the external source at JP9, 
and the SMA Connector J52. 

2.

 

To use the on-board oscillator, install Jumper JP11. To shut 
down the oscillator, remove Jumper JP11.  

3.

 

Set Jumper J50 in the 

OSC

 center position.  

4.

 

Alternatively, if the external master clock is available, it can 
either be connected at J52 as a coaxial 50 Ω SMA 
connector, or at JP9 as a 2-way header (0.1” pitch). If using 
JP9 as the source, install J50 in the 

PSIA

 position. If using 

J52 as the source, install J50 in the 

SMA

 position.  

5.

 

The MCLK is level shifted to the required IOVDD. By default, 
the level shifted master clock is used. Set Jumper J43 to the 

IOVDD

 position. Alternatively, if direct MCLK pin access 

is needed, set J43 to the 

3V3

 position. In this case, ensure 

that the master clock supplied to the 

ADAU1977

 is at the 

correct IOVDD level. 

6.

 

Two options are provided for the PLL filter, MCLK mode 
or LRCLK mode. By default, the MCLK mode is selected 

by installing Jumper J44 in the 

MCLK

 position. If the 

LRCLK mode is required, set J44 in the 

LRCLK

 position. 

In the I

2

S output section, take the following steps:  

1.

 

Determine the serial data format used for the ADC output. 
Either I

2

S/left justified (LJ)/right justified (RJ)/TDM 

format or SPDIF format are available.  

For I

2

S/LJ/RJ/TDM format, take the following steps: 

1.

 

Set LK3 and LK5 to the 

I

2

S

 position. 

2.

 

Set LK1 and LK2 to the 

I

2

S

 position. 

3.

 

Set Switch S13 to the 

MASTER

 position if the 

ADAU1977

/

ADAU1978

/

ADAU1979

 is used as a master for 

the serial audio port. Alternatively, it can be set to the 

SLAVE

 position; however, in this case, both the LRCLK 

(frame clock) and the BCLK (bit clock) must be provided 
from an external source. 

4.

 

The buffered serial output is available on the J26 (4-way 
dual row, 0.1” pitch) header. Alternatively, the direct 
(unbuffered

ADAU1977

 serial outputs are available on the 

J25 (8-way dual row, 0.1” pitch) header. 

For SPDIF format, take the following steps: 

1.

 

Ensure LK3 and LK5 are set to the 

SPDIF

 position. 

2.

 

Ensure LK1 and LK2 are set to the 

SPDIF

 position. 

3.

 

Ensure LK4 is set to the desired serial data pair. Either 
Pair 1 (Ch1 and Ch2) or Pair 2 (Ch3 and Ch4) can be 
selected because only 2-channel SPDIF output is available 
on the evaluation board.  

4.

 

Ensure LK6 is set to the 

SPDIF

 position which provides 

the MCLK to the SPDIF transmitter.  

5.

 

The SPDIF output is available on U16 as an optical form or 
on J35 as a coaxial form. 

For the I

2

C/SPI control section, take the following steps: 

1.

 

Slide Switches S3, S4, and S5 are used to set the control 
communication protocol for the 

ADAU1977

. 

For I

2

C protocol, take the following steps:  

1.

 

Set Switches S3, S4, and S5 to the 

I

2

C

 position. 

2.

 

Ensure JP6 is not installed. 

3.

 

The device address for th

ADAU1977

 is set using 

Switch S9. The possible 7-bit device addresses are 0x11, 
0x31, 0x51, or 0x71. The 

EVAL-ADAU1977Z

 evaluation 

board is set for the 0x71 address. 

4.

 

The 20-way (10-pin, dual row, 0.1” pitch), Shrouded 
Connector J8 is used to connect the supplied USBi. 
Alternatively, any other I

2

C master controller can be 

connected at J8 to control the 

ADAU1977

. 

5.

 

The Analog Devices, Inc., USBi is the quickest way to set 
the 

EVAL-ADAU1977Z

 board using the supplied 

standalone GUI or SigmaStudio™ software.
