GENERAL DESCRIPTION

This board is designed to allow the user to evaluate the perfor-

mance of the ADF4351 frequency synthesizer for phase-locked

loops (PLLs). Figure 1 shows the board, which contains the

ADF4351 integrated synthesizer and VCO, SMA connectors for

the output signal, power supplies, a reference oscillator, and an

USB connector. There is also a loop filter (35 kHz) on board.

The evaluation board is set up for a 25 MHz PFD comparison

frequency. An on-board TCXO provides the 25 MHz reference

frequency.

The package also contains Windows® software (XP or later) to

allow easy programming of the synthesizer.
