Low noise, frequency selectable XOs and VCXOs

The frequency select pins are used to select the output frequency from any combination of two or four preconfigured frequencies. According to Rakon, the selectable capability increases design flexibility and reduces part count, to generate significant cost savings. The RXO7050Q and RVX7050Q deliver a frequency output from 8MHz to 1.5GHz with <1ps RMS phase jitter (integrated 12kHz to 20MHz), to address high speed serial data communications, networking and telecom applications. Rakon states that the Q Series offer a low cost, pin compatible alternative to SiLabs proprietary Si5xx selectable oscillators. The company plans to release smaller footprint versions in the near future.
