EVAL-ADF4351EB1Z

The EVAL-ADF4351EB1Z is an Evaluation Board for the ADF4351 fractional-N PLL frequency synthesizer. This board is designed to allow the user to evaluate the performance of the ADF4351 frequency synthesizer for phase-locked loops (PLLs). The board 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 (35kHz) on board. The evaluation board is set up for a 25MHz PFD comparison frequency. An on-board TCXO provides the 25MHz reference frequency. The EVAL-ADF4351EB1Z has two SMA output connectors (differential outputs). The device is quite sensitive to impedance unbalance. If only one port of a differential pair is used, terminate the other with a 50R load.
