Diodes Incorporated PI6C20800SAE

Description
The PI6C20800S is a PCI Express, high-speed, low-noise differential clock buffer designed to accompany the PI6C410BS PCI Express clock generator for Intel server chipsets. It distributes the differential SRC clock from the PI6C410BS to eight differential pairs of clock outputs with or without a 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. When the 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.
