Programmable PLL Frequency Timing Generator Single 28-Pin SSOP T/R

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.

• 4 - 0.7 V HCSL differential output pairs
• Supports Serial-ATA at 100 MHz
• Two spread spectrum modes: 0 to -0.5 downspread and +/-0.25% enterspread
• Unused inputs may be disabled in either driven or Hi-Z state for power management
• M/N Programming
