The 843031-01 is an 10Gb Ethernet Clock Generator and a member of the family of high performance devices from IDT. The 843031-01 uses an 18pF parallel resonant crystal. The 843031-01 has excellent <1ps phase jitter performance, over the 1.875MHz - 20MHz integration range. The 843031-01 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One differential 3.3V or 2.5V LVPECL output
  • Crystal oscillator interface designed for 25MHz, 18pF parallel resonant crystal
  • Output frequencies: 280MHz – 340MHz
  • VCO range: 560MHz - 680MHz
  • RMS phase jitter @ 312.5MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.46ps (typical)
  • Full 3.3V or 2.5V operating supply
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
