PI6C20800 is a high-speed, low-noise differential clock bufferdesigned to be a companion to PI6C410B. The device distributesthe differential SRC clock from PI6C410B to eight differentialpairs of clock outputs either with or without PLL. The inputSRC clock can be divided by 2 when SRC_DIV# is LOW. Theclock outputs are controlled by input selection of SRC_STOP#,PWRDWN# and SMBus, SCLK and SDA. When input of eitherSRC_STOP# or PWRDWN# is LOW, the output clocks areTristated. When PWRDWN# is LOW, the SDA and SCLK inputsmust be Tristated.
