NOTICE - The following device(s) are recommended alternatives:

The 843202I is a 2 output LVPECL Synthesizer optimized to generate Gigabit Ethernet and SONET reference clock frequencies and is a member of the family of high performance clock solutions from IDT. Using a 19.44MHz and 25MHz, 18pF parallel resonant crystal, 155.52MHz and 156.25MHz frequencies can be generated. The part also allows the use of a recovered clock at QB output. The 843202I uses IDT's FemtoClockTM low phase noise VCO technology and can achieve 1ps or lower typical RMS phase jitter. The 843202I is packaged in a 32-pin LQFP package.

特性

  • Two 3.3V LVPECL outputs
  • Selectable crystal oscillator interface or one differential recovered clock inputs
  • Supports the following output frequencies: 155.52MHz and 156.25MHz
  • VCO range: 560MHz - 680MHz
  • RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal (12kHz – 1.3MHz): 0.86ps (typical)
  • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz –- 20MHz): 0.56ps (typical)
  • Full 3.3V supply mode
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
