ICS840001I - CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

Datasheet Summary

Description

The ICS840001I is a Fibre Channel Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS.

The ICS840001I uses a 26.5625MHz crystal to synthesize either 106.25MHz or 212.5MHz, using the FREQ_SEL pin.

Features

  • 1 LVCMOS/LVTTL output, 7Ω typical output impedence.
  • Crystal oscillator interface designed for 26.5625MHz, 18pF parallel resonant crystal.
  • Selectable 106.25MHz or 212.5MHz output frequency.
  • VCO range: 560MHz to 680MHz.
  • RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal (637kHz - 5MHz): 0.70ps (typical).
  • 3.3V or 2.5V operating supply.
  • -40°C to 85°C ambient operating temperature.
