OCXO 10MHz Frequency Reference Module Reference Source Low Phase Noise for Sound System Decoder Frequency Meter No Cable Portable, small size, and lightweight design with a green working indicator. USB TYPE-C interface for 5V 1A power supply, compatible with mobile phone chargers and power banks. High accuracy 10MHz frequency source derived from OCXO technology. Frequency accuracy of 10.000000MHz ± 0.1PPM (ta=23±5℃). Advanced temperature compensation technology to enhance frequency stability and minimize temperature impact. YMC-06S is a 10MHz Frequency Reference with sine and square wave 2-in-1 device. It adopts a 10MHz OCXO constant temperature crystal oscillator as the frequency reference source, ensuring good stability and super low noise, making it a reliable choice for upgrading instruments, communication systems, and audio systems. Although YMC-06S uses USB 5V as a power supply, many high-frequency EMI filter elements have been incorporated to minimize EMC interference issues.
