Description

The PI6CB332001 is a 20-output very low power PCIe® Gen 1/Gen 2/Gen 3/Gen 4/Gen 5 and Gen 6 clock buffer. It is capable of distributing the reference clocks for UPI, SAS, SATA, and other applications as well. It takes a reference input to fanout twenty 100MHz low power differential HCSL outputs with on-chip terminations. The on-chip termination can save 80 external resistors and make layout easier. OE pins combined with SMBus bits as well as 3-wire side band interface provide easier power management for each output.

It uses Diodes' proprietary design to achieve very low jitter that meets PCIe Gen 1/Gen 2/Gen 3/Gen 4/Gen 5 and Gen 6 requirement.
