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
