9FG108EGLFT

DATASHEET FREQUENCY GENERATOR FOR CPU, QPI, FBD, PCIE GEN1/2 & SATA ICS9FG108E Description Features/Benefits 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. • Generates common frequencies from 14.318MHz or Recommended Application Frequency Generator for CPU, PCIe Gen1/2, SATA and USB3.0 • • • • • • • Output Features • 8 - HCSL differential outputs • 1 - 3.3V REF output (either 14.318M or 25M depending on XTAL) 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 Key Specifications • • • • • Cycle to cycle jitter: < 50ps Phase jitter: PCIe Gen1/2
