TEST POINTS
There are numerous test points on the EVAL-AD7262/AD7264.
These test points enable the user to have easy access to the
signals for probing, evaluation, and debugging.
OPERATING WITH THE EVAL-CED1Z BOARD
The evaluation board can be operated in a standalone mode or
operated in conjunction with the EVAL-CED1Z board. This
evaluation board controller is available from Analog Devices
under the order entry EVAL-CED1Z.
When interfacing the EVAL-AD7262/AD7264 directly to the
EVAL-CED1Z board, all supplies and control signals to operate
the EVAL-AD7262/AD7264 are provided by the EVAL-CED1Z.
The AD7264 can operate at 1 MSPS with SCLK frequencies up
to 34 MHz while the AD7262 can operate with a 40 MHz SCLK.
The SCLK frequency supplied by the EVAL-CED1Z is fixed at
34 MHz for the AD7264 and 40 MHz for the AD7262. The
software allows the user to change the throughput rate by
effectively modifying the
CS
high time.
Software to communicate with the EVAL-CED1Z and AD7262
or AD7264 is provided with the EVAL-AD7262/AD7264 package.
The 96-way connector on the EVAL-AD7262/AD7264 plugs
directly into the 96-way connector on the EVAL-CED1Z.
The EVAL-CED1Z provides all the supplies for the evaluation
board. It is powered from a 7 V, 15 W power supply, which
accepts input voltages from 100 V to 240 V ac and contains
the relevant adaptors for worldwide use. The power supply is
provided with the EVAL-CED1Z.
Connection between the EVAL-CED1Z and the USB port of a
PC is via a standard USB 2.0 connection cable that is provided
as part of the EVAL-CED1Z package.
