Oscillators are electronic circuit elements which have the ability to generate relatively constant oscillations, either by themselves or when they are coupled with other components. The TA-4.000MCE-T is one such oscillator, primarily designed for applications involving frequency stabilization in communication equipment. This document covers the application field and working principle of the TA-4.000MCE-T in greater detail.

The TA-4.000MCE-T is a miniature voltage-controlled temperature-compensated crystal oscillator (MCXO). It is small in size and is designed to be used in environments with a temperature range from -40°C to +85°C. Its main features include low phase noise, low long-term ageing and high output frequency stability over temperature and time. It is available in a variety of crystalcut configurations from 10.000MHz to 70.000MHz, and is widely used in applications such as serial clocking, high-performance clock multiplication and data transmission within communication systems.

The TA-4.000MCE-T uses a standard SMD package and has a control voltage range of +2.0V to +3.3V, making it easy to integrate into existing system architectures. The device is housed in a hermetically sealed metal case and offers protection from ESD and other environmental effects. The working principle of the device is based on a voltagecontrolled temperature-compensated oscillator (VCTCXO). The oscillator itself is made up of an amplifier, a voltage-controlled crystal oscillator (VCXO), a temperature-compensated crystal oscillator (TCXO), and a frequency divider.

The amplifier is used to amplify the low-level signals from the voltage-controlled crystal oscillator. The VCXO is a crystal oscillator whose frequency is controlled by the amplitude of the voltage applied to it. The TCXO is used to provide better temperature stability over the operating temperature range (-40°C to +85°C). Finally, the frequency divider is used to reduce the crystal oscillator frequency down to the desired value. This entire process helps to achieve frequency stability over time and temperature.

In summary, the TA-4.000MCE-T is an oscillator that is designed to provide frequency stability in a wide range of communication systems. It uses a voltage-controlled temperature-compensated oscillator to achieve high frequency stability over temperature and time. It is small in size and is housed in a hermetically sealed metal case for improved ESD protection. It is a widely used device due to its low phase noise, low ageing and high output frequency stability.
