INTERFACING THE EVALUATION BOARD TO THE
EVAL-CED1Z
Interfacing the EVAL-CED1Z board to the evaluation board is
via a 96-way connector, J1. The pinout for the J1 connector is
shown in Figure 2. Table 9 gives a description of the pins on the
96-way connector that are used to interface the EVAL-CED1Z
to the EVAL-AD7265/AD7266.

TEST POINTS
There are two test points on the inputs to the AD7265/AD7266
on the evaluation board. Test points enable the user to have easy
access to various signals on the EVAl-AD7265/AD7266, facilitat-
ing probing, evaluation, and debugging.
