optical connectors.
Windows PC software provides a GUI to make configuration easy in Software Mode. The software
communicates through the PC’s parallel port to control
the internal registers so that all the possible software
modes of the CS8416 and CS8406 may be tested.

CDB8416
1. OVERVIEW
The CDB84166 evaluation board contains a
CS8416 and a CS8406 and the supporting circuitry
necessary to operate them. The board provides balanced XLR and unbalanced optical and coaxial inputs and outputs as outlined in the AES3 and
IEC60958 standards. In Software Mode, the control registers of the CS8416 and CS8406 are set by
a Windows based program through the parallel port
of a PC.
1.1 CS8416 and CS8406
The features and functions of the CS8416 and the
CS8406 are described in their respective data
sheets.
1.2 Parallel Port
To use the CS8416 and CS8406 on the board in
Software Mode, the parallel port on the upper right
hand side of the board should be connected to the
parallel port of the PC running the CDB8416 control software.
1.3 Serial Digital Audio Inputs
The left edge of the board is occupied by a row of
serial digital audio input connectors. In either
Hardware or Software Mode the user must select
which inputs are to be used via the switch setting,
INPUT, on switch S3.
Set the switch to the open position to select the
XLR balanced input which will use the RXP1 and
RXN inputs of the CS8416.
Set the switch to the closed position to select the
optical/coaxial unbalanced inputs which will use
the RXP0 and RXP2 through RXP7 inputs of the
CS8416. This will AC couple the RXN input to
GND. Note that in Hardware Mode, only RXP0
through RXP3 on the CS8416 are available for use.
To select between the inputs in Hardware Mode,
use the RXSEL0 and RXSEL1 switches on S3.
1.4 Serial Digital Audio Outputs
The right edge of the board is occupied by the serial
digital audio outputs. The optical S/PDIF output is
always enabled. The user may also choose to enable either the coaxial S/PDIF output or the XLR
AES3 output via jumper J11. These outputs are
transformer coupled.
1.5 Three-wire (PCM) Serial Audio Input and Output
Header J18 is provided so the user may access the
three wire serial audio ports of the receiver and
transmitter. The purpose of this port is to allow the
user to connect external circuitry such as a DAC,
ADC, or DSP to the receiver and transmitter. Signals going into or out of these headers should be
operated at VL+.
Setting switch S1-M/S
CS8416 as the master and the CS8406 as slave for
LRCK and SCLK. Setting switch S1-M/S in the
closed position sets the CS8406 as the master and
the CS8416 as slave for LRCK and SCLK.
Setting switch S3-8416_PCM to the open position
will turn off all of the input/output buffers for the
CS8416. Setting switch S4-8406_PCM to the open
position will turn off all of the input/output buffers
for the CS8406. These switches allow the user to
independently set the input and output for the
CS8416 and CS8406.
in the open position sets the
1.6 Crystal Oscillators
Oscillator Y1 provides the System Clock (OMCK)
for the CS8416. The crystal oscillator on the board
is mounted in pin sockets that allow it to be removed or replaced. The board is shipped with a
12.288 MHz crystal oscillator stuffed at Y1, setting
the output sampling rate to 48 kHz. Please refer to
the CS8416 data sheet for details on OMCK operation.

Several LEDs are provided to indicate board functions. D9 indicates that power is present to the
VD+/VA+ section of the CS8416 and CS8406.

3. BOARD SETUP
3.1 Power Supplies:
1) Verify that all power supplies are off before
making connections.
2) Connect a +3.3 V DC power supply to the
VD+/VA+ (J6) binding post and place jumper
J8 in the ADJUST position. This connection
may be omitted by setting J8 to the REG position. VD+/VA+ will be derived from the onboard +3.3V regulator.
3) Connect a +3.3 V to +5.0 V DC power supply
to the VL+ (J5) binding post and place jumper
J7 in the ADJUST position. This connection
may be omitted by setting J7 to the +5 V position. VL+ will be derived from the +5 V binding post.
4) Connect a +5.0 V DC power supply to the +5 V
(J3) binding post.
5) Connect the common ground of the power supplies to the GND (J4) binding post.
6) Apply power to the board. D9 should illuminate indicating power is applied to VD+/VA+.
3.2 Hardware Mode Settings:
1) Place switch S1-H/S in the OPEN position.
2) Place switches S3-INPUT, S3-8416_PCM, S3NVSEL, S3-RXSEL1, S3-RXSEL0, S3TXSEL1, S3-TXSEL0, S1-M/S, S1-SFMT1,
S1-SFMT0, S4-8406_PCM, S4-TCBLD, S4CEN to the appropriate positions.
3) Press and release the RESET switch S3. The
board should now be setup for use in Hardware
Mode.
3.3 Software Mode Settings:
effect Software Mode operation.
3) Press and release the RESET switch S2. The
board should now be setup for use in Software
mode.
4) Connect a DB-25 parallel port cable from the
PC’s parallel port to J1 on the CDB8416.
3.3.1 Installing the Software:
1) Create a directory called CDB8416 anywhere
on your system.
2) Copy CDB8416.exe from the included CD into
this directory.
3) Run port95nt.exe from the CD. After running
the program the system will need to be restarted.
4) If desired, create a shortcut to CDB8416.exe on
your desktop. You should now be able to run
CDB8416.exe.
5) Double-click on CDB8416.exe or its shortcut.
6) Click on the button on the lower right labeled
“Advanced”.
7) Select the LPT port you are using to connect to
the CDB8416.
8) Shut down the application, reset the board, and
then restart the application.
3.3.2 Verifying Board Operation:
1) In the “CS8416 AES Receiver Controls” window, select the check box “Enable Internal
Clocks” (enables the RUN bit in the Clock
Control register).
2) In the “CS8406 AES Transmitter Controls”
window, select the check box “Enable Clocks”
(enables the RUN bit in the Clock Control register).
1) Place switch S1-H/S in the CLOSED position.
2) Place switches S1-M/S, S3-INPUT, S38416_PCM, and S4-8406_PCM to the appropriate positions. All other switch setting do not
DS578DB3 7
3) In the “CS8416 AES Receiver Controls” window, select the check box “Generate
SCLK/LRCK”. Make sure that switch S1-M/S
is in the OPEN position.

4) Check the performance of the board by doing
an FFT with a -1 dBFS 1 kHz sine wave for input at a 48 kHz sample rate using the optical input and optical output.
4. CDB8416.EXE USER'S GUIDE
4.1 Main Window
The main window of the CDB8416 Control Application allows the user to view the configuration of
the CS8416. Clicking the left mouse button on the
CS8406 Controls button will bring up a control
panel containing all the register bits relevant to that
part.
Clicking on the Advanced button at the lower right
brings up the Advanced Options control panel.
Within the Advanced Options you may read and
write hex values into specified registers in either
part. Changes made on the CS8406 or CS8416 control panels will also be immediately reflected in the
Main Window, so you may wish to arrange them so
that they do not obscure each other.
