Distributes one differential clock input pair to five differential

clock output pairs.

2.5V AV operation and differential data input and output levels.

The device is a zero delay buffer that distributes a differential clock

input pair (CLK, CLK) to five differential pairs of clock outputs

(Y[0:4], Y[0:4]) and one differential pair feedback clock outputs

(FBOUT, FBOUT). The clock outputs are controlled by the input

clocks (CLK, CLK), the feedback clocks (FBIN,FBIN), and the

Analog Power input (AV ). When the AV is strapped low, the
