Description
ICS9FG108D is a Frequency Timing Generator that provides 8
differential output pairs that are compliant to the Intel CK410
specification.
It also 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 50
ps and output-to-output skew of less than 65 ps. ICS9FG108D 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 < 65 ps
+/-300 ppm frequency accuracy on output clocks
+/-50 ppm at any frequency with spread off
Features/Benefits
Generates common frequencies from 14.318 MHz or
25 MHz
Crystal or reference input
8 - 0.7V current-mode differential output pairs
Supports Serial-ATA at 100 MHz
Two spread spectrum modes: 0 to -0.5 down spread
and +/-0.25% center spread
Unused inputs may be disabled in either driven or Hi-Z
state for power management.
