INTERFACING THE EVALUATION BOARD TO THE
EVAL-CED1Z
Interfacing the EVAL-CED1Z to the AD7352/AD7356/AD7357
evaluation board is via a 96-way connector, J1. The pinout for the
J1 connector is shown in Figure 2. Tabl e 4 provides a description
of the pins used on the 96-way connector, and Table 5 details
the pin designations.
