A line of space-qualified crystal oscillators (XOs) from Bliley Technologies  includes oven-controlled crystal oscillators (OCXOs), temperature-compensated crystal oscillators (TCXOs), and voltage-controlled crystal oscillators (VCXOs).

The oscillators, which meet the requirements of MIL-PRF-3098 for space use, are available with frequencies from 10 to 130 MHz. Optimized for low phase noise, the oscillators feature excellent frequency versus temperature stability. In manufacturing the low-noise oscillators, the company employs Class “S”, JANS, JANTX, Established Reliability, and MIL-STD-883 screened components, with workmanship standards meeting the requirements of MIL-STD-454, MIL-STD-2000, and NHB5300.4.
