UG-609
MODES OF OPERATION
SDP CONTROLLED MODE
The AD7903 uses a high speed serial interface that allows sampling
rates of up to 1 MSPS. For more information about the operation of
the serial interface, refer to the AD7903 data sheet.
The AD7903 uses the serial interface to transfer data to the
EVAL-SDP-CB1Z.
The EVAL-AD7903SDZ communicates with the EVAL-SDP-CB1Z
board using level shifters. The EVAL-SDP-CB1Z operates at a
3.3 V logic level, which allows logic voltages that exceed 3.3 V
to be used without damaging the SDP interface.

STANDALONE MODE
The EVAL-AD7903SDZ can also be used without the EVAL-SDP-
CB1Z controller board. In this case, the EVAL-AD7903SDZ is
connected to the serial interface using the J5 connector or the
test points. For more information about the operation of the
serial interface, refer to the AD7903 data sheet.
