Description

9FG108 is a Synthesizer 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.
