Overview
The AD9515BCPZ is a two-output clock distribution IC designed by Analog Devices Inc. to emphasize low jitter and phase noise, thereby maximizing the performance of data converters. This IC features two independent clock outputs, with one output configured as LVPECL and the other output configurable to either LVDS or CMOS levels. The LVPECL output operates up to 1.6 GHz, while the other output operates up to 800 MHz in LVDS mode and up to 250 MHz in CMOS mode. Each output includes a programmable divider that can be set to divide by integers ranging from 1 to 32, and a divider phase select function for coarse timing adjustments.
