ICS9FG104
IDTTM/ICSTM
Frequency Generator for CPU, QPI, FBD, PCIe Gen 2 & SATA
0839O—12/03/08
Frequency Generator for CPU, QPI, FBD, PCIe Gen 2 & SATA
DATASHEET

Description
The ICS9FG104 is a Frequency Timing Generator that provides 4
differential output pairs that are compliant to the Intel CK410
specification. It also provides support for PCI-Express and SATA.
The part synthesizes several output frequencies from either a
14.31818 Mhz crystal or a 25 MHz crystal. The device 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. The ICS9FG104 also provides a copy
of the reference clock. Frequency selection can be accomplished via
strap pins or SMBus control.
Key Specifications
Output cycle-to-cycle jitter < 50 ps
Output to output skew < 35 ps
+/-300 ppm frequency accuracy on output clocks
+/- 150 ppm frequency accuracy @ 100 MHz outputs
28-pin SSOP/TSSOP package
Available in RoHS compliant packaging
Features/Benefits
Generates common frequencies from 14.318 MHz or
25 MHz
Crystal or reference input
4 - 0.7V current-mode differential output pairs
Supports Serial-ATA at 100 MHz
Two spread spectrum modes: 0 to -0.5 downspread
and +/-0.25% centerspread
Unused inputs may be disabled in either driven or Hi-Z
state for power management.
