PI6CB18200
Very Low Power 2-Output PCIe Clock Buffer
Description
Features
e DIODES PI6CB18200 is an 2-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 two 100MHz low power differential HCSL outputs.
