VCSO Based Clock Generator

The M926-02 is a PLL (Phase Locked Loop) based clock generator that uses an internal VCSO (Voltage Controlled SAW Oscillator) to produce a very low jitter output clock. From the M926-02-622.0800, an output clock frequency of 622.08 or 155.52MHz is provided from six LVPECL clock output pairs. (Other frequencies are available; consult factory.) The accuracy of the output frequency is assured by the internal PLL that phase-locks the internal VCSO to the reference input frequency (19.44MHz for the M926-02-622.0800). The input reference can either be an external crystal, utilizing the internal crystal oscillator, or a stable external clock source such as a packaged crystal oscillator.


  • Output clock frequency range 150MHz to 700MHz (Consult factory for frequency availability)
  • Selectable divider chooses one of two frequencies
  • Six identical LVPECL output pairs (same frequency)
  • Jitter 0.7ps rms (@622.08MHz, over 12kHz-20MHz), typ.
  • Ideal for OC-48/STM-16 clock reference
  • Output-to-output skew < 100ps
  • External XTAL or LVCMOS reference input
  • Selectable external feed-through clock input
  • STOP clock control (Logic 1 stops output clocks)
  • Integrated SAW (surface acoustic wave) delay line
  • Single 3.3V power supply
  • Small 9 x 9 mm SMT (surface mount) package
