20.5x20.5x11.0mm
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 radar systems, synthesizers, test & measurement instrumentation, GPS tracking and cellular base stations. Frequency stability to ±5ppb with low phase noise is available.
