Setup

Connect the 120-pin connector on the EVAL-CN0371-SDPZ

circuit board to the CON A connector on the EVAL-SDP-CB1Z

SDP-B board. Use nylon hardware to firmly secure the two boards,

using the holes provided at the ends of the 120-pin connectors.

Test

Launch the evaluation software and connect the USB cable

from the PC to the mini-USB connector on the SDP-B board.

When USB communications are established, the SDP-B board

can send, receive, and capture data from the circuit board.

Figure 6 shows a photo of the circuit board connected to the

SDP-B board. Information regarding the SDP-B board can be

found in the UG-277 User Guide.

Information and details regarding test setup, calibration, and

how to use the evaluation software for data capture can be

found in the CN-0371 Software User Guide.

Connectivity for Prototype Development

The EVAL-CN0371-SDPZ circuit board is designed for use with

the EVAL-SDP-CB1Z SDP-B board; however, any microprocessor

can be used to interface to the SPI interface of the AD7192. For

another controller to be used with the EVAL-CN0371-SDPZ

circuit board, software must be developed by a third party.

There are existing interposer boards that can be used to interface

to the Altera and Xilinx field programmable gate arrays (FPGAs).

The BeMicro SDK board from Altera can be used with the

BeMicro SDK/SDP interposer using nios drivers. Any Xilinx

evaluation board that features an FMC connector can be used

with the FMC-SDP interposer board.

The EVAL-CN0371-SDPZ is also compatible with the Digilent,

Imod interface specification.

Figure 6 shows a photo of the system test setup. Complete

documentation including schematics, layouts, Gerber files, and

bill of materials can be found in the CN0371 Design Support

Package at www.analog.com/CN0371-DesignSupport .
