PI6C557-05B - PCIe 3.0 Clock Generator

General Description

The PI6C557-05B is a spread spectrum clock generator compliant to PCI Express® 3.0 and Ethernet requirements.

The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI).

The PI6C557-05B provides four differential (HCSL) or LVDS spread spectrum outputs.

Key Features

  • PCIe® 3.0 complaint →PCIe 3.0 Phase jitter: 0.48ps RMS (High Freq. Typ. ).
  • LVDS compatible outputs.
  • Supply voltage of 3.3V ±5%.
  • 25MHz crystal or clock input frequency.
  • HCSL outputs, 0.7V Current mode differential pair.
  • Jitter 40ps cycle-to-cycle (typ).
  • Spread of -0.5%, -1.0%, -1.5%, and no spread.
  • Industrial temperature range.
  • Spread Bypass option available.
  • Spread and frequency selection via ex.
