637V156H6A3T working principles

637V156H6A3T is based on the Pierce oscillator architecture where a quartz crystal is the four-port network. It consists of an amplifier, two capacitors and a quartz crystal resonator. The capacitors act as a high-frequency filter, which performs a frequency-selective coupling between input and output. The amplifier amplifies the signal, which is then sent to the quartz crystal resonator. The quartz crystal resonator has a predictable frequency determined by its own physical dimensions, which creates the oscillation. The oscillation is then reconstituted through the filter with the appropriate phase.

The circuit is designed to use the quartz crystal in the Pierce oscillator architecture, where the quartz crystal determines the oscillation frequency. The crystal oscillator also features a built-in ESR (equivalent series resistance) to create additional stability. The frequency range of the circuit is determined by the specific characteristics of the quartz crystal resonator.

Conclusion

637V156H6A3T is a low-power, surface mount oscillator with features such as high long-term stability, low jitter, very low power consumption, and excellent reliability. It can be used in a variety of consumer, communication and automotive applications.
