Diodes Incorporated PI6CB332001 Gen4/Gen5 Clock Buffer

Diodes Incorporated PI6CB332001 Gen4/Gen5 Clock Buffer is a 20-output low-power clock buffer that is capable of distributing the reference clocks for UPI, SAS, and SATA. This clock buffer takes a reference input to fan out twenty 100MHz low power differential High-Speed Current Steering Logic (HCSL) outputs with on-chip terminations. The on-chip termination comes with the ability to save 80 external resistors and to make the layout easier. The OE pins combined with SMBus bits and 3-wire sideband interface provide easy power management for each output. The PI6CB332001 clock buffer offers low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirement. This clock buffer supports Intel DB2000QL specification and comes in a small 6mm x 6mm package.
