EVALUATION BOARD

Hardware

The AD9873-EB is an evaluation board for the AD9873 analog

front end converter. Careful attention to layout and circuit design

allow the user to easily and effectively evaluate the AD9873 in

any application where high-resolution, and high-speed conversion

is required. This board allows the user flexibility to operate the

AD9873 in various configurations. Several jumper or solder bridge

settings are available. The ADC inputs can be differentially

driven by transformers or by an AD8138 when using connector

J8 as the only input. Differential to single-ended transmit output

options include direct transformer coupled or filtered (75 MHz)

and variable gain amplified by the AD8323. Digital transmit

(Tx) inputs are designed to be driven from various word generators

and allow for proper load termination.

Software

The AD9873-EB software provides a graphical user interface

that allows easy programming and read back of AD9873 register

settings. Three programming windows are available. The Direct

back in decimal, binary or hexadecimal data format. The register

map window provides a very easy, function orientated program-

ming of AD9873 bits and registers. Programming hints appear

when the cursor is moved over an input field. Registers are

updated on every WRITE button click. The advanced register

access window allows programming of register access sequences.
