GENERAL DESCRIPTION

The AD9514 features a multi-output clock distribution IC in a design that emphasizes low jitter and phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements also benefit from this part.

There are three independent clock outputs. Two of the outputs are LVPECL, and the third output can be set to either LVDS or CMOS levels. The LVPECL outputs operate to 1.6 GHz, and the third output operates to 800 MHz in LVDS mode and to 250 MHz in CMOS mode.
