Description
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.
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.
