Resonator: CSTCE12M0G55Z-R0 Application Field and Working Principle

Resonators are small electronic devices used to generate a constant frequency or increase the frequency stability in various electronic circuits. The CSTCE12M0G55Z-R0 is a Tuning Fork crystal resonator with low power consumption and a wide frequency range from 18.432MHz to 19.2MHz. It is widely used in CMOS oscillators, transponders, and other electronic devices.

Application Fields

The CSTCE12M0G55Z-R0 is suitable for use in a variety of area and applications including base station access technologies, BluetoothTM, Gigabit Ethernet switches and routers, ISM frequency oscillators, mobile phones, RFID transponders, wifi devices, and ZigBeeTM equipment. Additionally, they are also be used in IoT devices, automotive, surveillance and home automation systems.

Working Principle

Tuning Fork crystal resonators are an improved version of the basic oscillator circuit that produces a preferred frequency. The working principle of the CSTCE12M0G55Z-R0 is based on electromechanical coupling between the electrostatic point between the oscillating metal plates of the resonator and the base electrode.The crystal resonator consists of two metal plates each with a rounded tip. Electrostatic force between the metal plates causes the metal plates to become oppositely charged and creates a resonant vibration frequency. The metal plates are called “tuning forks” as they vibrate at the specific frequency determined by the length and shape of the metal plates.The metal plates are anchored at a single support point and the vibration of the plates creates electrical pulses. These electrical pulses are fed to an external circuit and the frequency of the pulses is determined by the frequency of the tuning fork. This frequency can be accurately controlled by adding or removing metal from the tuning fork resonator. The precision of the frequency control is enhanced by the use of onboard capacitors and resistors.

Advantages and Limitations of the CSTCE12M0G55Z-R0

The CSTCE12M0G55Z-R0 has many advantages as a Tuning Fork crystal resonator, including low power consumption, low manufacturing cost, and a wide frequency range. It also has a long product life, and is highly reliable with a frequency stability of +/-0.5ppm.However, the CSTCE12M0G55Z-R0 has a few limitations.
