TC-44.000MCE-T

Oscillators

TC-44.000MCE-T oscillator is one of the frequently used oscillators in audio and numeric signal processing. It is a temperature and frequency-controlled crystal oscillator used widely in consumer electronics and telecommunications. It involves as an integral part of tuning, reception, and transmission of radio waves and is also used for wide-band frequency synthesis.

Application Field and Working Principle

The TC-44.000MCE-T oscillator is usually used in audio video, and telecommunications. Examples include cordless telephone, MEMS-based guidance systems, short range RFID systems, and Bluetooth. This oscillator makes it easy to modulate digital signals with great accuracy and reliability due to its low power consumption and low jitter.

The working principle of the TC-44.000MCE-T oscillator is based on the oscillator circuit integration with a temperature sensing device. The oscillator uses an oscillator frequency that is linearly proportional to the frequency of a quartz crystal. The frequency ranges from 30 MHz to 60MHz and is monitored by a built-in temperature sensor. The temperature sensor can supply a control voltage to the oscillator to correct the frequency drift due to environment or other external influences.

The TC-44.000MCE-T is composed of two main components, the resonator and the circuit. The resonator is composed of two electrodes and a quartz crystal. The electrodes are used to supply the electrical power to the quartz crystal which will then cause it to vibrate, producing a alternating electrical signal. The circuit has a gain control loop and a phase-shift feedback circuit to keep the output frequency of the oscillator stable.

The output frequency of the oscillator is determined by the temperature-varying behavior of the control voltage combined with the high stability of the quartz crystal. The oscillator stability is further improved with the control loop and the phase-shift feedback circuit. The input power source and the external temperature both have an impact on the output frequency. The temperature range of -40°C to +85°C allows for operation in an extremely wide range of temperatures. Moreover, the operating voltage range of TC-44.000MCE-T is from 2.7 V to 5.5 V.

In summary, the TC-44.000MCE-T oscillator is a high-performance, temperature-controlled crystal oscillator suitable for a wide range of applications. It has a low power consumption and low jitter, making it a great choice for audio video, and telecommunications. The built-in temperature sensor then corrects the frequency drift due to environment or other external influences.
