AD9865
EVALUATION BOARD
independent monitoring of the ac power line. The evaluation
board allows complete optimization of power line reference
designs based around the AD9865 or AD9866.
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.
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 a calibrated differential input signal to be
injected into its front end.
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
