DATASHEET Frequency Generator for CPU, QPI, FBD, PCIe Gen 2 & SATA ICS9FG104 Features/Benefits 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 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.

ICS9FG104

Features/Benefits

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

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.
