Description
Pericom Semiconductor's PI6C20400A is a PCIe® 2.0 compliant
high-speed, low-noise differential clock buffer designed to be
companion to PI6C410BS. The device distributes the differential
SRC clock from PI6C410BS to four differential pairs of clock
outputs either with or without PLL. The clock outputs are
controlled by input selection of SRC_STOP#, PWRDWN# and
SMBus, SCLK and SDA. When input of either SRC_STOP#
or PWRDWN# is low, the output clocks are Tristated. When
PWRDWN# is low, the SDA and SCLK inputs must be Tri-stated.
