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.
