Description

The PI6CBF18501 is a 5-output, very low power PCIe Gen1/Gen2/Gen3/Gen4 clock buffer. The device takes a reference input to fanout 100MHz low power differential HCSL outputs with on-chip terminations. The on-chip termination saves 24 external resistors and makes layout easier. Individual OE pins for each output provides
easier power management. The device uses Diodes' proprietary design to achieve very low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4 requirements. It provides various advanced options, such as different slew rates
and amplitudes through SMBus so users can easily configure the device to achieve the optimized performance for their individual boards.
