Description

The PI6CB33801 is an eight-output very-low-power PCIe Gen1/ Gen2/Gen3/Gen4/Gen5 clock buffer. It takes a reference input to fanout eight 100MHz low-power differential HCSL outputs with on-chip terminations. The on-chip termination can save 32 external resistors and make layout easier. Individual OE pin for each output provides easier power management.


It uses Diodes proprietary PLL design to achieve very-low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirements.
Other than PCIe 100MHz support, this device also supports Ethernet application with 50MHz, 125MHz, and 133.33MHz via
SMBus. It provides various options such as different slew rate and amplitude through SMBUS, so users can configure the device easily to get the optimized performance for their individual boards.
