Oscillators are devices that produce a periodic electrical waveform whose frequency and amplitude stay consistent for a specific period of time. The M675-01-BE is one type of oscillator used in many applications. This article will outline the specific features of this oscillator, its application field and working principle.

The M675-01-BE is a temperature controlled quartz crystal oscillator (TCXO). This type of oscillator is designed to maintain a very steady frequency over a wide range of temperatures. To accomplish this, each unit contains a thermistor that measures the temperature around the oscillator and keeps the clock frequency stable. This type of oscillator is particularly well-suited for systems that are exposed to extreme temperatures, or for applications that require precise timing.

M675-01-BE is a stable oscillator with excellent performance in the fields of GPS, mobile communication, radio, radio navigation and broadcast communications. Its core frequency range is 8.25 MHz to 40 MHz, and its frequency accuracy over a temperature range of -40 °C to +85 °C is ±2.5 ppm. Its vibration resistance is less than 20g, and it also has low power consumption of 2.0 mW.

The M675-01-BE features an exceptionally low phase noise of -134 dBc/Hz at 10 kHz offset. This provides excellent performance in applications requiring low jitter, such as clock synchronization and synchronous data transmission. The oscillator has a range of operational voltages, including 3.3 V DC, 5.0 V DC and 12.0 V DC, making it suitable for a variety of applications.

The working principle of the M675-01-BE is relatively simple. The oscillator has a quartz crystal that is precisely cut at a frequency that is tuned to vibrate at a certain frequency when a current is passed through it. The frequency is adjusted by varying the current while applying a voltage across the device. This voltage is sensed by the thermistor, which adjusts the voltage to keep the frequency constant despite changes in temperature. The signal is then sent through the amplifier, which amplifies the signal and output it as an oscillating voltage.

In conclusion, the M675-01-BE is a temperature controlled quartz crystal oscillator that is well-suited for applications requiring temperature compensated frequencies and low jitter. Its main application fields are GPS, mobile communication, radio, radio navigation and broadcast communications, where its strength lies in its stability and low phase noise. The main components of this oscillator are the quartz crystal, the thermistor, and the amplifier. Understanding the working principle of this oscillator will help designers and engineers make sure that they are using the right type of oscillator for the job.
