Overview

Description

The 843011 is a Fibre Channel Clock Generator. The 843011 uses a 26.5625MHz crystal to synthesize 106.25MHz or a 25MHz crystal to synthesize 100MHz. The 843011 has excellent <1ps phase jitter performance, over the 637kHz – 10MHz integration range. The 843011 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One differential 3.3V LVPECL output
  • Crystal oscillator interface designed for 26.5625MHz 18pF parallel resonant crystal
  • Output frequency: 106.25MHz or 100MHz
  • VCO range: 560MHz - 680MHz
  • RMS phase jitter @ 100MHz, using a 25MHz crystal (637kHz - 10MHz): 0.80ps (typical)
  • RMS phase noise at 106.25MHz Phase noise:
    Offset                  Noise Power
     100Hz .............. -92.8 dBc/Hz
        1kHz ............. -119.6 dBc/Hz
      10kHz ............. -129.5 dBc/Hz
    100kHz ............. -130.5 dBc/Hz
  • 3.3V operating supply
  • Available in lead-free (RoHS 6) package
  • -40°C to 85°C ambient operating temperature
