... PLL_BW# PLL 06-0011 Description PI6C20800 is a high-speed, low-noise differential clock buffer designed companion to PI6C410B. The device distributes the differential SRC clock from PI6C410B to eight differential pairs of clock outputs either with or without PLL. The input SRC clock can be divided by 2 when SRC_DIV# is LOW. The clock outputs are controlled by input selection of SRC_STOP#, PWRDWN# and SMBus, SCLK and SDA ...
