The Renesas Electronics ICS9FG104E is a frequency generator that provides 4 differential HCSL output pairs. It can be used to drive PCIe Gen1/2, SATA and USB3.0 devices. The part can use either a 14.31818 MHz or 25 MHz crystal. The 9FG104E can also be driven by a reference input clock instead of a crystal. It provides outputs with cycle-to-cycle jitter of less than 50 ps and output-to-output skew of less than 35 ps.

Generates common frequencies from 14.318MHz or 25MHz
Crystal or reference input
4 - 0.7V current-mode HCSL output pairs
Supports Serial-ATA at 100MHz
Two spread spectrum modes: -0.5% down spread and +/-0.25% center spread
