PI6CG182Q中文资料2-Output PCIe Gen 4 Clock Generator for Automotive Applications数据手册Diodes规格书

描述 Description

The PI6CG182Q 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 spreadspectrum options to reduce EMI for Automotive applications.
