Overview
The AD9514BCPZ-REEL7, produced by Analog Devices Inc., is a multi-output clock distribution IC designed to emphasize low jitter and phase noise. This component is particularly suited for applications requiring high-performance clocking, such as data converter clocking, where subpicosecond jitter is crucial for maximum converter performance. The device features three independent clock outputs, with two outputs operating at LVPECL levels up to 1.6 GHz and the third output configurable to either LVDS (up to 800 MHz) or CMOS (up to 250 MHz) levels. The AD9514 does not require an external controller for operation and is programmed using 11 pins with 4-level logic. It operates from a single 3.3 V supply and is available in a 32-lead LFCSP package with a temperature range of −40°C to +85°C.
