The 843004I-01 is a 4 output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz. The 843004I-01 uses IDT's 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 843004I-01 is packaged in a small 24-pin TSSOP package.

Features

  • Four 3.3V differential LVPECL output pairs
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
  • Supports the following output frequencies: 156.25MHz, 125MHz, 62.5MHz
  • VCO range: 560MHz – 680MHz
  • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz – 20MHz): 0.54ps (typical)
  • Full 3.3V or 2.5V supply modes
  • -40°C to 85°C ambient operating temperature
  • Available in and lead-free (RoHS 6) package
