ICS844023I - CRYSTAL-TO- LVDS CLOCK GENERATOR

General Description

The ICS844023I is an Ethernet Clock Generator and a member of the HiPerClocksTM family of high HiPerClockS™ performance devices from ICS.

The ICS844023I uses an 18pF parallel resonant crystal over the range of 24.5MHz - 34MHz.

For Ethernet applications, a 25MHz crystal is used to generate 250MHz.

Key Features

  • One Differential LVDS output.
  • Crystal oscillator interface, 18pF parallel resonant crystal (24.5MHz - 34MHz).
  • Output frequency range: 245MHz - 340MHz.
  • VCO range: 490MHz - 680MHz.
  • RMS phase jitter @ 250MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.38ps (typical).
  • 3.3V or 2.5V operating supply.
  • -40°C to 85°C ambient operating temperature.
  • Available in both standard and lead-free RoHS-compliant packages.
