The IDT5V41234 is a PCIe Gen2/3 compliant spread spectrum capable clock generator. The device has 1 differential HCSL output and can be used in communication or embedded systems to subtantially reduce electro-magnetic interference (EMI). Spread spectrum can be enabled via a select pin.

Features

  • 1 - 0.7V current mode differential HCSL output pairs
  • 16-pin VFQFPN package; very small board footprint 
  • Spread-spectrum capable; reduces EMI 
  • Outputs can be terminated to LVDS; can drive a wider variety of devices
  • Spread enable via pin selection; no software required to configure device
  • Industrial temperature range available; supportsdemanding embedded applications
  • Cycle-to-cycle jitter <100 ps 
  • PCIe Gen2 phase jitter <3.0ps RMS
  • PCIe Gen3 phase jitter <1.0ps RMS
