ICS8430252-45 - FEMTOCLOCKS CRYSTAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER

General Description

The ICS8430252-45 is a 2 output LVPECL and LVCMOS/LVTTL Synthesizer optimized to genHiPerClockS™ erate Ethernet reference clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions from ICS.

Key Features

  • One differential 3.3V LVPECL output and One LVCMOS/LVTTL output.
  • Crystal oscillator interface designed for a 25MHz, 18pF parallel resonant crystal.
  • A 25MHz crystal generates both an output frequency of 156.25MHz (LVPECL) and 125MHz (LVCMOS).
  • VCO frequency: 625MHz.
  • RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz) using a 25MHz crystal: 0.39ps (typical).
  • Full 3.3V supply mode.
  • 0°C to 70°C ambient operating temperature.
  • Industr.
