Analog DevicesAD9520-3/PCBZ

The AD9520 evaluation board is a compact, easy-to-use platform for evaluating all features of the AD9520.

The AD9520-x (hereafter referred to as AD9520) is a very low noise PLL clock synthesizer featuring an integrated VCO, clock dividers, and up to 24 outputs. The AD9520 features automatic holdover and a flexible reference input circuit allowing for very smooth reference clock switching. The AD9520 family also features the necessary provisions for an external VCXO.
