Frequency Translation PLL

The M2004-01 is a VCSO (Voltage Controlled SAW Oscillator) based clock generator PLL designed for clock frequency translation and jitter attenuation in a high-speed data communications system. The clock multiplication ratio and output divider ratio are pin selectable and also configurable through serial programming. External loop components allow the tailoring of PLL loop response.


  • Ideal for OC-48/192 data clock
  • Integrated SAW (surface acoustic wave) delay line
  • VCSO frequency from 300 to 700MHz (Specify VCSO center frequency at time of order)
  • Low phase jitter of < 0.5ps rms, typical (12kHz to 20MHz or 50kHz to 80MHz)
  • Pin-selectable or serially programmed configuration
  • The M2004-11 adds Hitless Switching with Phase Build-out (HS/PBO) to ensure SONET/SDH MTIE and TDEV compliance during reference clock reselection
  • Reference clock inputs support single-ended LVCMOSLVTTL
  • Industrial temperature available
  • Single 3.3V power supply
  • Small 9 x 9 mm SMT (surface mount) package
