Overview

The M2006-03 is a VCSO (Voltage Controlled SAW Oscillator) based clock generator PLL designed for frequency translation and jitter attenuation of a master reference clock in a cable modem termination system (CMTS). External loop filter components allow tailoring of the PLL loop response. The M2006-03 includes a phase-slope limiting feature to prevent disruptive output clock phase changes upon input reference reselection.

m2006-03 - Pinout
  • Integrated SAW (surface acoustic wave) delay line
  • VCSO center frequency of 491.52MHz
  • Jitter 9ps rms, typical, over 100Hz to 12kHz Jitter 3ps rms, typical, over 12kHz to 1GHz
  • PLL phase slope limiter circuit
  • Single-ended reference inputs support LVCMOS, LVTTL
  • All output clocks are differential LVPECL compatible
  • Two downstream clocks, frequency-selectable
  • One upstream clock, frequency-selectable
  • REF_OUT always provides a 10.24MHz reference clock
  • All output rising edges aligned to within 1nsec of selected input reference rising edge (unless M2_SEL= 1)
  • Output duty cycle 47-53% worse case
  • Single 3.3V power supply
  • Small 9 x 9 mm SMT (surface mount) package
