PI6CB18601
Very Low Power 6-Output PCIe Clock Buffer With On-chip Termination
Description
Features
e DIODES PI6CB18601 is an 6-output very low power PCIe® yꢀ1.8V Supply Voltage
Gen1/Gen2/Gen3/Gen4 clock buffer. It takes an reference input yꢀHCSL Input: 100MHz, also support 50MHz or 125MHz via
to fanout eight 100MHz low power differential HCSL outputs
