Working Principles

At its core, the AX7PBF2-1244.1600T is an analog oscillator, meaning it uses an amplitude-controlled oscillating device to generate a periodic waveform. It takes the input of a quartz tuning fork crystal oscillator and the output is a voltage-controlled oscillator (VCO).The quartz tuning fork consists of two electrodes on opposite sides that vibrate in response to an electrical pulse. The output generated is a sine wave with a precise frequency. This frequency is responsible for the accuracy and stability of the oscillator’s output.The output signal is then put through a unique frequency multiplication stage to reach the target frequency and voltage swing while maintaining the desired accuracy. This process is done through a voltage-controlled oscillator (VCO), which is a simple but effective technique for frequency multiplication.The input/output impedance of the AX7PBF2-1244.1600T is optimized for best signal integrity, ensuring the highest possible precision and reliability. This oscillator features European standard temperature range with ESR (equivalent series resistance) tolerance of ±100ppm. Its supply voltage ranges from 3V-3.6V ensuring a wide frequency range of 320Hz to 800kHz with low-power consumption features.In conclusion, the AX7PBF2-1244.1600T is a versatile quartz-based oscillator with a wide range of features enabling it to be the best suitable choice for many applications and industries, such as industrial, automotive, and medical imaging systems. Its robust and cost-effective design helps make it a preferred choice for many designers, as well as providing good levels of accuracy and precision.
