Working Principle of SG-615PH 50.0000MC0:ROHS

The SG-615PH 50.0000MC0:ROHS is a temperature-compensated crystal oscillator (TCXO) that employs an optimized temperature compensated voltage-controlled crystal oscillator (TCVCXO) circuit. This oscillator is based on a quartz crystal controlled oscillator (QCA), which means that the circuit uses a quartz crystal as the frequency reference for the oscillator. A quartz crystal is made up of a pair of plates, with a positive and negative charge applied to each plate. When a voltage is applied to one of the plates, an oscillating electric field is established between the two plates. This field vibrates the quartz crystal, which produces a frequency that is proportional to the voltage applied to the crystal.The TCXO in the SG-615PH 50.0000MC0:ROHS is designed with a thermistor on the rear of the unit. The thermistor measures the temperature of the environment and then sends a signal to the TCVCXO circuit. The TCVCXO circuit adjusts the voltage on the quartz crystal in order to compensate for temperature changes. This ensures that the output frequency is maintained at a consistent level, regardless of the environmental conditions.

Conclusion

The SG-615PH 50.0000MC0:ROHS is a popular and reliable TCXO oscillator designed for low-cost, low-power, and non-critical timing applications. Its temperature compensated voltage-controlled crystal oscillator circuit allows for precise frequency control, ensuring that the output frequency is maintained at a consistent level regardless of environmental conditions. With its wide range of application fields and reliable performance, the SG-615PH 50.0000MC0:ROHS is the ideal choice for many timing applications.
