Analog Devices Inc. AD9516-4BCPZ

Description
The AD9516-4 is a multi-output clock distribution device with an integrated 1.6 GHz VCO and PLL. It features low phase noise and jitter performance, making it suitable for applications requiring precise timing. The device has six LVPECL outputs (in three pairs) and four LVDS outputs (in two pairs), each with programmable dividers and coarse phase delay. The LVDS outputs can be reconfigured as CMOS outputs. The AD9516-4 is available in a 64-lead LFCSP and operates from a single 3.3 V supply.
