Datasheet	PI6LC4820 Datasheet

The PI6LC4820 is an LC VCO based low phase noise design intended for 10GbE applications.

Typical 10GbE usage assumes a 25Mhz crystal input, while the PLL loop is used to generate the 156.25MHz outputs.

An additional buffered crystal oscillator output is provided to serve as a low noise reference for other circuitry.
