AK8160B2
Low Power & Low Jitter Clock Generator for PCI Express
1. General Description
The AK8160B2 is a member of AKM’s low power and low jitter clock generator family designed for PCI
Express generation 2.0. This device has one PLL with spread spectrum (SS) function and enables to output
high quality differential 100MHz as PCI Express clock and 25MHz as reference simultaneously.
