OX-172
Oven Controlled Crystal Oscillator
OX-172
The OX-172 is a high stability ovenized crystal oscillator characterized for IEEE-1588 PTP applications in a 28 x 38 mm package.
Driven by an SC cut crystal, the oscillator provides TDEV and MTIE values that exceed the GR1244 system performance
requirements when locked through a 1 mHz bandwidth. The OX-172 is designed for operation during congested network
conditions, when the frequency and quality of the packet information is degraded. The OX-172 is a member of the OX-17 oscillator
series. Other oscillators in the series include the OX-170 standard oscillator, OX-171 high stability oscillator, 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. Please contact the factory for customization options.
