PI6CG18201ZDIEX

The PI6CG18201 is an 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 with on-chip terminations. The on-chip
termination can save 8 external resistors and make layout easier.
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.
