5.000M~120.000MOven Controlled Crystal Oscillator(OCXO) POC2525
The POC2525-MHz series OCXO (temperature-controlled Crystal oscillator) launched by Zhejiang A-Crystal has a frequency range of 5.0M to 120.000MHz, featuring ultra-low phase noise (-100 DBC/Hz@10Hz) and excellent frequency stability (±0.3ppm initial accuracy). The product adopts SMD 2525 packaging and supports electrical frequency modulation (±2.5ppm), and is suitable for high-precision fields such as microwave communication, radar systems, and medical equipment. Features include fast startup (stable within 5 minutes), low power consumption (2.1W), compliance with RoHS standards, and passing MIL-STD environmental tests to ensure industrial-grade reliability.
