Programmable FTG for Differential P4^TMCPU, PCI-Express & SATA

Clocks

ICS9FG107

Description

Features/Benefits

ICS9FG107 is a Frequency Timing Generator that provides 7

differential output pairs that are compliant to the Intel CK409/CK410

specification. It provides support for PCI-Express, next generation I/

O, 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 85 ps and

output-to-output skew of less than 85 ps.

•

Generates common CPU/PCI Express frequencies from

14.318 MHz or 25 MHz

•

Crystal or reference input

7 - 0.7V current-mode differential output pairs

3 - 33MHz PCI outputs

1 - REFOUT

Supports Serial-ATA at 100 MHz

Two spread spectrum modes: 0 to -0.5 downspread and

+/-0.25% centerspread

ICS9FG107 also provides a copy of the reference clock and 333

MHz PCI output clocks. Frequency selection can be accomplished

via strap pins or SMBus control.

•

Unused inputs may be disabled in either driven or Hi-Z

state for power management.

Key Specifications

•

Output cycle-to-cycle jitter for DIF outputs < 50 ps (<85ps

@ 266 MHz)

•

Output to output skew for DIF outputs < 85 ps

+/-300 ppm frequency accuracy on output clocks

48-pin SSOP/TSSOP package

Available in RoHS compliant packaging
