RENESAS 9FG108EGILFT

The ICS9FG108E is a Frequency Generator that provides 8 differential HCSL output pairs. It can be used to drive PCe Gen1/2, SATA and USB3.0 devices. The part can use either a 14.31818 Mhz or 25 MHz crystal. The ICS9FG108E 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.

• 8 - HCSL differential outputs
• 1 - 3.3V REF output (either 14.318M or 25M depending on XTAL)
• Generates common frequencies from 14.318MHz or 25MHz
• Crystal or reference input
• 8 - 0.7V current-mode HCSL output pairs
• Supports Serial-ATA at 100MHz
• Two spread spectrum modes: -0.5% down spread and +/-0.25% center spread; Lower EMI
• 31.5KHz spread modulation rate; passes USB3 compliance testing
• Unused outputs may be disabled in either driven or Hi-Z state for power manangement
• I-temp version available; supports embedded applications
• Cycle to cycle jitter: <50ρs
• Phase jitter: PCIe Gen1/2 <3ps rms
• Output to output skew <65ρs
• +/-300 ppm frequency accuracy on output clocks
• +/-50ppm on all output frequencies with Spread Off

• Frequency Generator for CPU, PCIe Gen1/2, SATA and USB3.0
