ICS9FG104D - Frequency Generator

General Description

The ICS9FG104D 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.

Key Features

  • Benefits.
  • Generates common frequencies from 14.318 MHz or 25 MHz.
  • Crystal or reference input.
  • 4 - 0.7V current-mode differential output pairs.
  • Supports Serial-ATA at 100 MHz.
  • Two spread spectrum modes: 0 to -0.5 downspread and +/-0.25% centers.

DATASHEET Frequency Generator for CPU, QPI, FBD, PCIe Gen 2 & SATA ICS9FG104D Description The ICS9FG104D 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 ICS9FG104D 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.
