Sige Single Frequency VCSO

The M690SDM is a single frequency/single output SAW-based VCSO for low-jitter clock generation. The M690SDM incorporates an analog X2 frequency multiplier to provide an output frequency that is twice that of the fundamental VCSO frequency.


  • Integrated SAW device
  • Low phase jitter: 250fs rms typical for the M690SDM (20kHz to 20MHz)
  • Output frequency: 1747 MHz Typ. (Specify center frequency at time of order)
  • Single-ended RF Output
  • Single +5V power supply
  • 13 x 20mm SMT (surface mount) package
  • Pb-free / Compliant to EC RoHS Directive (RoHS 5/6)
