The 842023 is an Ethernet Clock Generator and a member of the family of high performance devices from IDT. For Ethernet applications, a 25MHz crystal is used to generate 250MHz. The 842023 uses IDT 3rd generation low phase noise VCO technology and can achieve <1ps rms phase jitter, easily meeting Ethernet jitter requirements. The 842023 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One differential HSTL output pair
  • Crystal oscillator interface, 18pF parallel resonant crystal (24.5MHz – 34MHz)
  • Output frequency range: 245MHz – 340MHz
  • VCO range: 490MHz – 680MHz
  • RMS phase jitter at: 250MHz, using a 25MHz crystal (1.875MHz – 20MHz): 0.36ps (typical)
  • Full 3.3V or 2.5V output supply modes
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
