FemtoClock® Crystal-to-LVCMOS/LVTTL Clock Generator

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

The 840011 is a Fibre Channel Clock Generator and a member of the family of high performance devices from IDT. The 840011 uses a 26.5625MHz or 25MHz crystal to synthesize 106.25MHz or 100MHz respectively. The 840011 has excellent phase jitter performance, from 637kHz – 10MHz integration range. The 840011 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One LVCMOS/LVTTL output, 7Ω output impedence
  • Crystal oscillator interface designed for 26.5625MHz or 25MHz, 18pF parallel resonant crystal
  • Output frequency: 106.25MHz (typical)
  • VCO range: 560MHz to 680MHz
  • RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal (637KHz - 10MHz): 0.780ps (typical)
  • RMS phase noise at 125MHz:
    Offset                  Noise Power
    100Hz ............... -95.7 dBc/Hz
    1kHz ................. -121 dBc/Hz
    10kHz ............... -129 dBc/Hz
    100kHz ............. -129.6 dBc/Hz
  • 3.3V operating supply
  • -30°C to 85°C ambient operating temperature
  • Available in both standard (RoHS 5) and lead-free (RoHS 6) packages
  • Not Recommended for New Designs
  • For New Designs Use ICS840N011BGI
