The 843081I-01 is an Ethernet Clock Multiplier. The 843081I-01 accepts a crystal reference of 19.6MHz - 28MHz. The 843081I-01 has excellent 1ps or lower phase jitter performance, over the 1.875MHz - 20MHz integration range. The 843081I-01 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One differential LVPECL output
  • One crystal oscillator interface: 19.6MHz - 28MHz
  • Output frequency range: 490MHz - 700MHz
  • VCO range: 490MHz - 700MHz
  • RMS phase jitter @ 625MHz using a 25MHz reference (1.875MHz - 20MHz): 0.32ps (typical)
  • 3.3V or 2.5V operating supply
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free RoHS compliant package
