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-tooutput 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.
