New Class of Ultraprecise Quartz Oscillators Combining Lowest Noise and Minimal Allan Deviation

Operation of modern telecom, navigation, control and measurement systems requires reference frequency sources. Their performance actually determines the systems’ main characteristics. Frequency stability vs. temperature, long-term and short-term stabilities, and phase noise are the most important for many applications. Read this white paper about this topic.

Low Phase Noise OCXO: MV269

MV269wROHSMorion has released the new MV269, low noise OCXO in a small DIL14 package, measuring just 21 x 13 x 9.5 millimeters. Available 60 to 120 MHz, the MV269 has phase noise of -153 dBc/Hz at 1 kHz offset and <-170 dBc/10 kHz; sinewave or HCMOS. Works at 5 or 3.3 V. Temperature stability at <5E-8 from 0° to 60° C; frequency adjustment for external synchronization provided, but due to <1E-7/year aging may work as a stand-alone unit.
