CCSO-914X-245.760

CCSO-914X-245.760 True SineWave SAW Based Clock Oscillator 9×14mm SMD Ultra-Low Phase Noise 245.760 MHz SAW Clock 5 Volt 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.
