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.
For Ethernet applications other than 10GbE, programmable dividers allow for simultaneous output of 312.5, 156.25, and 125MHz.
