EVAL-AD9516-3

Product Details

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 user guide covers all six versions of the AD9516 family, as well as the AD9517 and AD9518 families (hereafter referred to as AD951x). 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.

Although the Quick Start Guide to the AD9516 PLL section applies specifically to the AD9516-3, increasing the N (feed-back) divider and channel divider increases the VCO frequency to the allowable frequency range of other AD9516 versions.

For the AD9516-5, which lacks an internal VCO, certain portions of this document that apply to the internal VCO (such as VCO calibration) can be ignored.
