Bomar Crystal is able to offer two ultra low tolerance surface mount (smd) Oven Controlled Crystal Oscillators. OCXOs are used for applications where frequency tolerance and stability are critical like Satellite Radios, Sonet Clocks, Synthesizers, Instrumentation and GSM Base Stations. Frequency stability to ±5ppb with low phase noise is available.
