10.000M~100.000MOven Controlled Crystal Oscillator(OCXO) POC2020
The POC2020-MHz series launched by Zhejiang A-Crystal is a high-performance SMD packaged oven-controlled crystal oscillator (OCXO) using SC-cut crystals, with a size of 20.6×20.6×11mm. The product has a nominal frequency range of 10.00~100.00MHz, excellent frequency stability of ±10ppb (operating temperature range 30°C to +70°C), and excellent phase noise performance, up to -150dBc/Hz at 10kHz offset. The product supports HCMOS output, standard load 15pF, operating voltage range 4.75~5.25V, and also provides a 3.3V voltage customization option. Its voltage control function can achieve a frequency adjustment range of ±0.5ppm, and the control voltage is 0~4V. This series of products is particularly suitable for application scenarios with strict timing requirements such as SDH/SONET systems, communication base station equipment, and high-precision test and measurement instruments.
