ICS9FG108D

Frequency Generator for CPU, QPI, FBD, PCIe Gen 2 & SATA DATASHEET ICS9FG108D Description ICS9FG108D is a Frequency Timing Generator 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. ICS9FG108D also provides a copy of the reference clock. Frequency selection can be accomplished via strap pins or SMBus control. Key Specifications Features/Benefits Generates common frequencies from 14.318 MHz or 25 MHz Crystal or reference input 8 - 0.7V current-mode differential output pairs Supports Serial-ATA at 100 MHz Two spread spectrum modes: 0 to -0.5 down spread and +...
