The IDT5V41285 is a PCIe Gen2 compliant clock generator. The device has 2 differential HCSL outputs. The output frequency is selectable via select pins.

Features

  • 16-pin TSSOP and VFQFPN packages; small board footprint
  • Outputs can be terminated to LVDS; can drive a wider variety of devices
  • OE control pin; greater system power management
  • Industrial temperature range available; supports demanding embedded applications
  • Cycle-to-cycle jitter: 80ps
  • Output-to-output skew <50 ps
  • PCIe Gen2 phase jitter <3.0ps RMS
  • Low phase noise: 12kHz to 20MHz <6ps
  • For PCIe Gen3 applications, see the IDT5V41315
