A modular SAW oscillator provides stable sinewave outputs at fixed available frequencies from 250 to 1090 MHz.
Model CCSO-914X is a surface-acoustic-wave (SAW) clock oscillator that can be supplied in single-frequency bands from 250 to 1090 MHz. Based on a SAW resonator and proprietary circuitry, the modular clock oscillator features -153 dBc/Hz phase noise offset 10 kHz from the carrier, with a noise floor of -173 dBc/Hz. The low-noise, low-jitter oscillator, which can run on +3.3- and +5-VDC supplies, generates a true sinewave output with minimum output power of +8 dBm and second harmonic levels of typically -20 dBc. It is designed for an operating temperature range from -40 to +85°C. The SAW clock oscillator is supplied in a surface-mount-technology (SMT) package measuring just 9 x 14 mm. It is priced at $36.96 in single-piece quantities.
