描述

The 843031 is a 1 Gigabit Ethernet clock generator. The 843031 can synthesize 1 Gigabit Ethernet, SONET, or Serial ATA reference clock frequencies with the appropriate choice of crystal and output divider. The 843031 has excellent phase jitter performance and is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

特性

  • One differential 3.3V LVPECL output
  • Crystal oscillator interface designed for 18pF parallel resonant crystals
  • Output frequency range: 290MHz - 350MHz
  • VCO frequency range: 580MHz - 700MHz
  • RMS phase jitter @312.5MHz (1.875MHz - 20MHz): 0.475ps (typical) RMS phase jitter @318.75MHz (1.875MHz - 20MHz): 0.475ps (typical)
  • 3.3V operating supply
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
