PI6C20400
Description
Pericom Semiconductors PI6C20400 is a high-speed, low-noise
differential clock buffer designed to be companion to PI6C410B.
The device distributes the differential SRC clock from PI6C410B
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 Tristated.
