CCSO-914X-245.760
Model CCSO-914X-245.760 is a 245.760 MHz SAW (surface acoustic wave) Clock
Oscillator (CCSO). SAW crystal technology provides low-noise and low-jitter
performance with true sinewave output. Features include -150 dBc/Hz phase noise at
10kHz offset, 5V input voltage, -40°C to +85°C operating temperature, FR5 PCB and
9×14 mm SMT package. The oscillator has no sub-harmonic and the second harmonic is
typically -20dBc.
Applications include:
System Clock for Network Clock Generator/Synchronizer, Clock for DDS, Test and
Measurement, Avionics, Point-to-Point Radios, and Multi-point Radios.
