Crystek Launches New 2.5 GHz RF Source

Crystek Microwave announces the release of a 2.5 GHz Phase Locked Clock Source with internal reference, the CRFS75-2500. Crystek designed the module using proprietary circuitry and SAW (surface acoustic wave) resonator technology to provide ultra-low jitter/phase noise performance with true SineWave output. The resulting source features -105 dBc/Hz phase noise at 10 KHz offset and a noise floor of -167 dBc/Hz.

Crystek’s CRFS75-2500 comes in a 0.75 in. x 0.75 in SMT package. With 5 V input voltage, it generates a true-sinewave with +5 dBm min. output power. The new source has no sub-harmonics; second harmonic is -20 dBc typical. Frequency stability is rated at +/- 25 ppm. The CRFS75-2500 operates from -20°C to +70°C.

Applications include: analog-to-digital (A/D) converters, system clocks for network clock generators/synchronizers; clocks for DDS; test and measurement; avionics; point-to-point radios; and multi-point radios.
