EVALUATION BOARD INTERFACING
Interfacing to the evaluation board is via a 96-way connec-
tor, J4. J4 is used to connect the evaluation board to the
EVAL-CONTROL BOARD or other system. The pinout
for the J4 connector is shown in Figure 2 and its pin des-
ignations are given in Table II.

96-Way Connector Pin Description
DR0
Data Receive Zero. This input is connected to the
SDATA pin of the AD7476/77.
TFS0/RFS0 Transmit/Receive Frame Sync Zero. These two
outputs are connected to the CS pin of the
AD7476/77.
SCLK0
Serial Clock Zero. This serial clock is connected
to the SCLK pin of the AD7476/77 with the
option of an inverting buffer.
DGND
Digital Ground. These lines are connected to
the digital ground plane on the evaluation
board. It allows the user to provide the digital
supply via the connector along with the other
digital signals.
AGND Analog Ground. These lines are connected to
the analog ground plane on the evaluation board.
AV_DD
+12V
Analog +5 V Supply. These lines are connected
to the AV_DD supply line on the board.
+12 V Supply. This line is connected to the +12
V supply line on the board via LK6.
-12V
-12 V Supply. This line is connected to the -12
V supply line on the board via LK7.
