Oscillators are devices that generate an AC signal. They are most often used for radio broadcasting, telecommunication systems, and other applications requiring an electrical signal with a consistent frequency. The 578L260IAT is an oscillator belonging to the family of Temperature Compensated Crystal Oscillators (TCXOs) marketed by Rakon. This article will provide an overview of the 578L260IAT’s application field and working principle.

First of all, the 578L260IAT is designed for everyday consumer use, such as mobile phone handsets, wireless microphones, medical equipment, car audio, GPS systems, and other applications requiring stable frequency control. Because this kind of TCXOs are designed to perform at the best accuracy and long-term stability while withstanding considerable temperature swings and vibration, the 578L260IAT makes a great choice for these consumer applications.

Advantages of the 578L260IAT include its stability and accuracy over wide temperature ranges. It has a frequency stability over temperature of +/- 10 ppm (20 ppm for higher temperatures), and a wide operating temperature range of -30-85°C. The device also has a vibration resistant construction, as well as high fast startup and low-current consumption. The 578L260IAT comes in a miniature surface-mount package measuring just 4.2 x 4.2 mm.

The 578L260IAT works on the principle of temperature compensated oscillator (TCXO). A TCXO has an internal oscillator loop, consisting of a quartz crystal and an amplifier. The amplifier amplifies the crystal oscillation signal and simultaneously modulates the frequency of oscillation. As the temperature changes, the frequency of the oscillator also changes. The frequency is compensated by the use of a temperature-sensitive electronic circuit, usually a thermistor, connected to the amplifier. The thermistor senses the temperature and adjusts the frequency of the oscillator to maintain stable frequency output.

This type of oscillator is also known as a voltage-controlled crystal oscillator (VCXO). The voltage-control is typically used to linearize the frequency variation which usually occurs in a TCXO over temperature. With a VCXO, the frequency of the oscillator can be adjusted over a wide range, with both positive and negative voltage control directions.

In summary, the 578L260IAT is an ideal choice for everyday consumer use, as its stability and accuracy over wide temperature ranges make it an excellent solution for applications requiring frequency control. The device, which functions on the principle of temperature compensated oscillator, has a frequency stability over temperature of +/- 10 ppm (20 ppm for higher temperatures), and a wide operating temperature range of -30-85°C. It also has the advantages of vibration-resistant construction, fast startup, and low-current consumption.
