GENERAL DESCRIPTION

The AD9512-EP provides a multi-output clock distribution in a design that emphasizes low jitter and low phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements can also benefit from this part.

There are five independent clock outputs. Three outputs are LVPECL (1.2 GHz), and two are selectable as either LVDS (800 MHz) or CMOS (250 MHz) levels.
