Description

The PI6CBF18501 is a 5-output, very low power PCIe Gen1/Gen2/

Gen3/Gen4 clock buffer. The device takes a reference input to

fanout100MHzlowpowerdifferentialHCSLoutputswithon-chip

terminations. The on-chip termination saves 24 external resistors

andmakeslayouteasier.IndividualOEpinsforeachoutputprovides

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.
