The PI6CB33401 is a 4-output very low power PCIe® Gen 1/Gen 2/Gen 3/Gen 4/Gen 5 clock buffer. It takes a reference input to fanout four 100MHz low power differential HCSL outputs with on-chip terminations. The on-chip termination can save 16 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 Gen 1/Gen 2/Gen 3/Gen 4/Gen 5 requirements. Other than PCIe 100MHz support, this device also support Ethernet application with 50MHz, 125MHz and 133.33MHz via SMBus. It provides various options such as different slew rate and amplitude through SMBUS so that users can configure the device easily to get the optimized performance for their individual boards.
