描述
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.
特性
- 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
