NOTICE - The following device(s) are recommended alternatives:

The 841602I is an optimized PCIe and sRIO clock generator and member of the family of high-performance clock solutions from IDT. The device uses a 25MHz parallel crystal to generate 100MHz and 125MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter (< 1ps rms) suitable to clock components requiring precise and low-jitter PCIe or sRIO or both clock signals. Designed for telecom, networking and industrial applications, the 841602I can also drive the high-speed sRIO and PCIe SerDes clock inputs of communication processors, DSPs, switches and bridges.

Features

  • Two differential clock outputs: configurable for PCIe (100MHz) and sRIO (125MHz) clock signals
  • Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or LVCMOS/LVTTL single-ended reference clock input
  • Supports the following output frequencies: 100MHz or 125MHz
  • VCO: 500MHz
  • PLL bypass and output enable
  • PCI Express® (2.5Gb/s) and Gen 2 (5 Gb/s) jitter compliant
  • RMS phase jitter, 125MHz, using a 25MHz crystal:
    (1.875MHz - 20MHz): 0.45ps (typical)
  • Full 3.3V power supply mode
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
