OX-171 Holdover Oscillators
6Pages

High Stability Oven Controlled Crystal Oscillator OX-171 The OX-171 is a high-stability ovenized crystal oscillator in a 28 x 38 mm package, capable of aging rates of 0.06 ppb/day and temperature stabilities of 1ppb over an industrial temperature range. Driven by an SC-cut crystal, the oscillator provides excellent phase noise and Allan Deviation. The OX-171 is a member of the OX-17 oscillator series. Other oscillators in the series include the OX-170 standard oscillator, OX-172 optimized for 1588 solutions, and the OX-174 and OX-175 low phase noise oscillators. The Vectron design team will also help develop custom solutions where performance optimization is required for specific applications.
