Description

The PI6CG33802C is an 8-output, very-low-power PCIe Gen1/ Gen2/Gen3/Gen4/Gen5 clock generator. It uses a 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 32 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/Gen5 requirements.
It also provides various options, such as different slew rate and amplitude through SMBUS, so users can easily configure
the device to get the optimized performance for their individual boards. The device also supports selectable spreadspectrum
options to reduce EMI for various applications.
