Description

The 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.

Features/Benefits

• 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; Lower EMI

• 31.5KHz spread modulation rate; passes USB3

compliance testing

• Unused outputs may be disabled in either driven or Hi-Z

state for power manangement

• I-temp version available; supports embedded

applications
