Frequency Translation PLL

The M2004 variants -02 and -12 are VCSO (Voltage Controlled SAW Oscillator) based clock generator PLLs 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. External loop components allow the tailoring of PLL loop response. The M2004-12 adds Hitless Switching with Phase Build-out (HS/PBO) to ensure that reference clock reselection does not disrupt the output clock.


  • 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 configuration
  • The M2004-12 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 differential LVDS, LVPECL, as well as single-ended LVCMOSLVTTL
  • Industrial temperature available
  • Single 3.3V power supply
  • Small 9 x 9 mm SMT (surface mount) package
