Oscillators: TC-66.667MCD-T Application Field and Working Principle

TC-66.667MCD-T oscillators are widely used in communication systems and a variety of electronic devices. By generating and regulating the accurate frequency signal, the oscillators enable the transmission and processing of radio waves, which make it possible for a device to receive and send signal from a remote source.

The TC-66.667MCD-T oscillator is a quartz crystal-based resonator with high frequency stability, low cost, and reliable performance. The oscillator comprises a crystal resonator, a temperature-compensated oscillator (TCXO), and a voltage-controlled oscillator (VCO). The crystal resonator generates a signal in response to an external input. The TCXO regulates this signal according to the temperature, producing a stable output with a frequency that is unaffected by temperature changes. The VCO modulates the signal by controlling the amplitude and shape of the output waveform.

The oscillator\'s application field mainly includes digital and analog communication systems such as satellite telecommunication systems, DVB television broadcasting, W-CDMA or CDMA2000 base station systems, 2.4GHz WiFi and Bluetooth, and digital mobile communication systems. It is also widely used in automotive electronic components, consumer electronics, and other electronics devices.

Working Principle of TC-66.667MCD-T Oscillator

The TC-66.667MCD-T oscillator works by generating a signal with a frequency that is determined by the crystal resonator and then modulated by the TCXO and VCO. The oscillator is made up of the temperature-compensated oscillator (TCXO) and the voltage-controlled oscillator (VCO), which are connected to each other via an external voltage input.

When a voltage is applied to the TCXO, it produces an alternating current signal that is in turn controlled by a precise frequency reference from the resonator. The TCXO is designed to maintain a fixed frequency with variations of no more than ±50 parts per million (ppm). The VCO produces a precisely tuned voltage output signal that is used to control the resulting frequency of the oscillator, which is typically in the kilohertz (kHz) range.

The TC-66.667MCD-T oscillator\'s frequency can be adjusted by changing the value of the external voltage. In order to ensure proper operation and accuracy of the oscillator, it is important to employ a careful method for applying the voltage.

Advantages of TC-66.667MCD-T Oscillator

A TC-66.667MCD-T oscillator offers several advantages over other types of oscillators.
