Oscillators

Oscillators are electrical circuits used to generate oscillating signals. They are widely used in various applications such as communication systems, automation systems, aerospace and military systems, radio circuit control, instrumentation, etc. An oscillator usually has an input signal, an amplifier, and a feedback element. It is designed to produce periodically repeated signals with recurrent waves.

TA-70.000MCD-T is a type of oscillator used in a wide variety of applications. It is a low-noise, low-drift, and temperature-compensated oscillator (TCO). It utilizes a low-power CMOS technology and is specifically designed for precision frequency control. The TA-70.000MCD-T has a E2CMOS® construction which allows for excellent stability and low-noise performance.

Application Field

The TA-70.000MCD-T oscillator is ideal for use in all kinds of precision frequency-control applications, such as crystal oscillators, clock oscillators, voltage-controlled oscillators, temperature-compensated crystal oscillators, and phase-lock frequency synthesizers. It is commonly used in a wide variety of communication systems, such as digital trunking systems, LTE base stations, WCDMA base stations, and femtocells. The TA-70.000MCD-T also finds applications in test and metrology equipment, precision clocks, and measuring instruments.

Working Principle

The TA-70.000MCD-T oscillator uses a temperature-compensated crystal oscillator (TCXO) technology to maintain stable output frequency. The principle of a TCXO is similar to that of a standard crystal oscillator, where a crystal element is placed in an LC (inductor-capacitor) resonant circuit. But a crystal oscillator’s performance is highly dependent on the environment temperature. A TCXO utilizes a special circuit to compensate the offset caused by a crystal element due to its temperature sensitivity. This circuit is known as a temperature-compensating network (TCN).

The TCN is made up of components like resistors and capacitors, and its design determines the amount of temperature compensation. The TCN is designed such that its components generate a parasitic frequency that offsets the frequency offset due to the environment temperature. This compensates the frequency error in the crystal oscillator, which allows it to maintain a stable frequency output.

The TA-70.000MCD-T oscillator has a TCN that has been optimized to achieve temperature stability over a -20°C to 50°C temperature range. It also has an adjustable frequency range of 0.3ppm/°C over a 2~200MHz frequency range. The TA-70.000MCD-T has integrated high-precision oscillator components, such as a low-current CMOS inverter, voltage-controlled crystal oscillator (VCXO), and temperature-compensating network (TCN). All these components work together to produce an output at a highly stable frequency over a wide temperature range.

Conclusion

The TA-70.000MCD-T oscillator is a useful and versatile tool for frequency control applications. It utilizes a highly efficient temperature-compensated crystal oscillator (TCXO) technology to maintain a stable output frequency. The TA-70.000MCD-T is ideal for use in a wide variety of communication systems, test and metrology equipment, precision clocks, and measuring instruments. It has integrated high-precision oscillator components, such as a low-current CMOS inverter, VCXO, and TCN, which work together to produce an output at a highly stable frequency over a wide temperature range.
