20.3x13.2x7.8mm
Bomar Crystal is able to offer a full line of ultra low tolerance thru hole 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 ±50ppb with low phase noise is available.
