Oscillators play a vital role in many kinds of systems from radio transmission and reception to digital signal processors in a computer. The 653L17505I3T is a piezo-ceramic oscillator that provides up to 25 MHz frequency stability with a fixed quartz crystal. This article will discuss the application field and working principle of this oscillator.

Application Field

The 653L17505I3T oscillator is suitable for applications such as radio broadcasting, television, medical instrumentation, military communication, and much more. It has a small size, making it suitable for a variety of applications. It has high output power, high frequency stability, and wide temperature range, making it ideal for the most demanding environments.

Due to its high level of integration, it is especially suitable for portable applications such as handheld radios, mobile phones, medical equipment, and automotive. It also has high reliability, which makes it suitable for applications in harsh environments such as aerospace and defense, as well as in commercial and industrial environments.

Working Principle

The 653L17505I3T oscillator utilizes a quartz crystal as its vibrator. The crystal is tuned to a specific frequency by cutting it with specific angles and thicknesses. This precision allows the crystal to oscillate with a specific frequency that is very stable. When a voltage is applied to the crystal, it begins to vibrate, and this vibration generates a radio frequency signal.

The oscillator also includes a circuit that amplifies this signal and feeds it back to the crystal in an endless loop, creating a sustained oscillation. This oscillation is then used to generate a clock signal with a defined frequency. The oscillator is very accurate, and it can maintain a frequency with less than one ppm variation over the temperature range of -40°C to +85°C.

In addition, the oscillator also includes additional functions such as a low-power on/off control circuit, an input signal conditioning circuit, an output signal conditioning circuit, and a phase-locked loop (PLL). All of these components work together to provide the user with a reliable and accurate signal.
