Features: 1.Adopting high quality electronic components, using precision technology to fine durability and long service life.2.Constant temperature 10MHz, ultra-low phase noise, low noise, portable and reliable.3.This product adopts 10MHz frequency standard, provided by OCXO furnace-controlled crystal oscillator.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.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 instruments marking.Product parameters:Name: Frequency Reference ModuleModel: OCXO-10MHzDSD sampling frequency: 2.8224 MHz (DSD64)PCM word length: 16 bitsPCM sampling rate: 44.1 kHzOutput: RCACurrent consumption: less than 750mA in warm-up phase, less than 300mA in operating phaseWarm-up time: 5 minutesCalibration accuracy: 0.01HzFrequency stability: 5e-12Output level: 10dBm 2dBm @ 50VRMS: 0.7071V @ 50VPeak: 1.0V @ 50-P: 2.0V @ 50Output Impedance: 50Connector Type: SMA external screws inside holesInterface Specification: DC5.5 x 2.1mmPCB board size: 66 x 43 x 13mmProduct 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 instruments reference.Material: PC+Metalcolour: blackPackage Contents:1 x frequency reference module1 x 9V battery connection cableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
