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

The 840001I-34 is a two output LVCMOS/LVTTL Synthesizer and a member of the family of high performance devices from IDT. One output is the LVCMOS/LVTTL main synthesized clock output (Q) and one output is a three-state LVCMOS/LVTTL reference clock (REF_OUT) output at the frequency of the crystal oscillator. The device can accept crystals from 15.3125MHz to 42.67MHz and can synthesize outputs from 81.67MHz to 213.33MHz. The 840001I-34 is packaged in a 3mm x 3mm 16-pin VFQFN, making it ideal for use on space constrained boards.

Features

  • Two LVCMOS/LVTTL outputs, 22Ω typical output impedance
    One main clock output (Q)
    One three-state reference clock output (REF_OUT)
  • Crystal oscillator interface can accept crystals from 15.3125MHz to 42.67MHz, 18pF parallel resonant crystal
  • Q output frequency range: 81.67MHz to 213.33MHz
  • RMS phase jitter @106.25, (637kHz – 10MHz): 0.38ps (typical)
  • VCO range: 490MHz to 640MHz
  • Full 3.3V and 2.5V operating supply
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
