PI6CG18200

Very Low Power 2-Output PCIe Clock Generator

Description

The PI6CG18200 is a 2-output very low power PCIe Gen1/Gen2/Gen3/Gen4 clock generator. It uses 25MHz crystal or CMOS reference as an input to generate the 100MHz low power differential HCSL outputs. An additional buffered reference output is provided to serve as a low noise reference for other circuitry.
It uses Diodes proprietary PLL design to achieve very low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4 requirements. It also provides various options such as different slew rate and amplitude through strapping pins or SMBUS so that users can configure the device easily to get the optimized performance for their individual boards. The device also supports selectable spread spectrum options to reduce EMI for various applications.
