EVALUATION BOARD

An evaluation board is available for the AD9865 and AD9866.

The digital interface to the evaluation board can be configured

for a half- or full-duplex interface. Two 40-pin and one 26-pin

male right angle headers (0.100 inches) provide easy interfacing

to test equipment such as digital data capture boards, pattern

generators, or custom digital evaluation boards (FPGA, DSP, or

ASIC). The reference clock source can originate from an exter-

nal generator, crystal oscillator, or crystal. Software and an

interface cable are included to allow for programming of the SPI

registers via a PC.

The analog interface on the evaluation board provides a full

analog front-end reference design for power line applications. It

includes a power line socket, line transformer, protection

diodes, and passive filtering components. An auxiliary path

allows independent monitoring of the ac power line. The

evaluation board allows complete optimization of power line

reference designs based around the AD9865 or AD9866.

Alternatively, the evaluation board allows independent evalua-

tion of the TxDAC, IAMP, and Rx paths via SMA connectors.

The IAMP can be easily configured for a voltage or current

mode interface via jumper settings. The TxDAC’s performance

can be evaluated directly or via an optional dual op amp driver

stage. The Rx path includes a transformer and termination

resistor, allowing for a calibrated differential input signal to be

injected into its front end.

the AD9865/AD9866 evaluation board.
