The AD9516-x, AD9517-x, and AD9518-x are very low noise PLL clock synthesizers featuring an integrated VCO, clock dividers, and up to 14 outputs. The AD9516 features automatic holdover and a flexible reference input circuit allowing for very smooth reference clock switching. The AD9516 family also features the necessary provisions for an external VCXO.
The AD9516 evaluation board is a compact, easy-to-use platform for evaluating all features of the AD9516. The AD9516, AD9517, and AD9518 differ only in package size, and the number of outputs. The evaluation software main window for the AD9517 and AD9518 reflects fewer outputs, but the operation is identical for all devices.
Use the user guide in conjunction with the AD9516, AD9517, and AD9518 data sheets.
