REV 0 11/00

GENERAL DESCRIPTION

This board is designed to allow the user to evaluate

the performance of the ADF4212 Frequency Synthe-

sizer for PLL's (Phase Locked Loops). The block

diagram of the board is shown below.

It contains the

footprint for a ADF4212 synthesizer, a pc connector,

SMA connector for the reference input, power sup-

plies and RF output. There is also a loop filter and a

VCO for both the RF and IF section on board. A

cable is included with the board to connect to a pc

printer port.

The package also contains Windows 95/98/NT soft-

ware to allow easy programming of the synthesizer.
