The 843023I is a Gigabit Ethernet Clock Generator and a member of the family of high performance devices from IDT. The 843023I uses a 25MHz crystal to synthesize 250MHz. The 843023I has excellent phase jitter performance, over the 1.875MHz – 20MHz integration range. The 843023I 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 frequency range: 240MHz - 320MHz
  • VCO range: 480MHz - 640MHz
  • RMS phase jitter @ 250MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.39ps (typical)
