Description
The PI6CFGL401B is an 4-output very low power clock genera-
tor for PCIe Gen1-2-3 applications with integrated output ter-
minations providing Zo=100Ω. The device has 4 output enables
for clock management and supports 2 different spread spectrum
levels in addition to spread off. The device also has one 1.8V
LVCMOS REF output.
