Description

The 9FG104 is a Synthesizer 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-to-output skew of less than 35 ps. Generates common CPU frequencies from 14.318 MHz or 25 MHz Crystal or reference input
