PI6LC4840 - Crystal to LVDS/LVCMOS Frequency Synthesizer

General Description

The PI6LC4840 is an LC VCO based low phase noise design intended for the most demanding Ethernet applications.

Common Ethernet frequencies of 25MHz and 125MHz are supported, with the 125Mhz having both LVDS and LVCMOS outputs for maximum flexibility.

Key Features
