8-Output PCIe Gen1-2-3 Clock Generator for Freescale Systems

The IDT6P41302 is an 8-output very low power clock generator for PCIe Gen1-2-3 applications with integrated output terminations providing Zo=100. The device has 8 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.

Features

  • 1.8V operation; reduced power consuption
  • 8 - 0.7V low-power HCSL-compatible (LP-HCSL) DIF pairs w/Zo=100ohm
  • 1 - 1.8V LVCMOS REF output w/Wake-On-LAN (WOL) support
  • DIF cycle-to-cycle jitter <50ps 
  • DIF output-to-output skew <50ps 
  • DIF phase jitter is PCIe Gen1-2-3 compliant 
  • REF phase jitter is < 1.5ps RMS
  • Outputs can optionally be supplied from any voltage between 1.05 and 1.8V; maximum power savings
  • OE# pins; support DIF power management
  • LP-HCSL differential clock outputs; reduced power and board space
  • Programmable Slew rate for each output; allows tuning for various line lengths
  • Programmable output amplitude; allows tuning for various application environments
  • Selectable 0%, -0.25% or -0.5% spread on DIF outputs; reduces EMI
  • External 25MHz crystal; supports tight ppm with 0 ppm synthesis error
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space saving 48-pin 6x6 mm VFQFPN; minimal board space
