SETUP CONDITIONS
Care should be taken before applying power and signals to the
evaluation board to ensure that all link positions are as per the
required operating mode. There are two different modes in
which to operate the evaluation board. The user can operate
the evaluation board with the EVAL-CED1Z, or it can be used
as a standalone board.
Table 2 shows the position in which all the links are set when
the evaluation board is packaged. When the board is shipped,
the assumption is that the user will operate with the EVAL-
CED1Z board. The links are set so that all power supplies and
control signals are supplied by the EVAL-CED1Z.

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 3 provides a description of the pins on the 96-way
connector used to interface between the EVAL-CED1Z board
and the EVAL-AD7280AEDZ. Table 4 gives the pin design-
nations for the 96-way connector.
