Block Diagram

Description

The PI6CFGL201B is a 2-output very low power 100MHz fre-

quency generator for PCIe Gen 1, 2 and 3 applications with inte-

grated output terminations providing Zo=100Ω. The device has

2 output enables for clock management and supports 2 different

spread spectrum levels in addtion to spread off. The device also

has one 1.8V LVCMOS REF1.8 output.
