Features: 1.Adopting high quality electronic components, using precision technology to ensure fine durability and long service life.<br> 2.Constant temperature 10MHz, ultra-low phase noise, low noise, portable and reliable.<br> 3.This product adopts 10MHz frequency standard, provided by OCXO furnace-controlled crystal oscillator.<br> 4. Constant temperature crystal oscillator means that this product uses a thermostatic bath to keep the temperature of the crystal oscillator or quartz crystal oscillator constant, thus minimising the change in oscillator output frequency caused by changes in ambient temperature and making it more accurately calibrated to an accuracy of ±0.01Hz.<br> 5. Equipped with SMA external screw inner hole interface. Widely used, can be used for audio system, decoder, short-wave radio, frequency meter, signal source and other inst ents marking.<br> Product parameters:<br> Name: Frequency Reference Module<br> Model: OCXO-10MHz<br> DSD sampling frequency: 2.8224 MHz (DSD64)<br> PCM word length: 16 bits<br> PCM sampling rate: 44.1 kHz<br> Output: RCA<br> Current consumption: less than 750mA in warm-up phase, less than 300mA in operating phase<br> Warm-up time: 5 minutes<br> Calibration accuracy: ±0.01Hz<br> Frequency stability: 5e-12<br> Output level: 10dBm ± 2dBm @ 50Ω<br> VRMS: 0.7071V @ 50Ω<br> VPeak: 1.0V @ 50Ω<br> VP-P: 2.0V @ 50Ω<br> Output Impedance: 50Ω<br> Connector Type: SMA external screws inside holes<br> Interface Specification: DC5.5 x 2.1mm<br> PCB board size: 66 x 43 x 13mm<br> Product Application: Constant Temperature 10MHz, Ultra-low Phase Noise, Frequency Reference Module, Frequency Reference Source, OCXO Frequency Reference Source, Used for audio system, decoder, shortwave radio, frequency counting source and other inst ents reference.<br> Material: PC+Metal<br> colour: black<br> Package Contents:<br> 1 x frequency reference module<br> 1 x 9V battery connection cable<br> Only the ab
