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.
