Crystals play a vital role in many electronic and communication products. This paper will discuss the application field and working principle of CMR310T-3.579545MABJ-UT, which is a crystal oscillator from Murata.

The CMR310T-3.579545MABJ-UT oscillator is a surface-mount, miniature electronic component that is designed to produce continuous, highly-accurate clock signal for various types of electronic circuits. It is typically used in applications such as microcontrollers, routers, and WLAN chipsets. It is also suitable for use in device communication systems, as a broadband receiver, and in medical instrumentation.

The CMR310T-3.579545MABJ-UT oscillator is based on the quartz crystal-type of oscillator mechanism. It consists of an oscillator circuit connected to a quartz crystal. This oscillator circuit includes a buffer, an amplifier, and a frequency divider. The quartz crystal is made of piezoelectric material and has the ability to vibrate at its resonant frequency. When an alternating voltage is applied to the crystal, the crystal vibrates at its resonant frequency. This vibration is then amplified and divided by the oscillator circuit and output as a clock signal.

The CMR310T-3.579545MABJ-UT oscillator has a frequency of 3.579545 MHz and a frequency tolerance of ±50 ppm (―parts-per-million‖). It has an operating temperature range of –40 to +85°C and a high storage temperature range of -45 to +125°C. Additionally, it has a high frequency stability and an extremely low phase noise of -135 dBc/Hz. It also features a voltage control function, which allows its frequency to be adjusted by applying a DC voltage between 0 and 5.5V. Furthermore, it has a low power consumption of 2.5mA and can be operated at voltages of 2.2V to 3.6V.

In addition to being used as an oscillator, the CMR310T-3.579545MABJ-UT can also be used as a high-speed switch. By applying a positive voltage, the crystal oscillator can be switched to its full-on state, and when a negative voltage is applied, it can be switched to its full-off state. This switching capability makes it an ideal choice for applications that require fast switching speeds.

The CMR310T-3.579545MABJ-UT is a reliable and versatile crystal oscillator that can be used in a variety of applications. Its high-accuracy frequency, wide temperature range, low phase noise, and voltage control function make it a great choice for any type of electronic circuit. The crystal oscillator is easy to integrate into a system and provides accurate frequencies that are essential for many communication systems. Its frequency switching capability also makes it a great choice for high-speed switching applications.
