353VB3A600R

The 353VB3A600R belongs to the family of oscillators, which are devices designed to generate a steady, repetitive signal. An oscillator is useful for a wide range of applications such as providing a reference signal for devices in radio and communication systems, frequency synthesizers, and more. So what is the application field and working principle of the 353VB3A600R?

The 353VB3A600R is a voltage controlled crystal oscillator (VCXO) designed for wireless communications applications in cellular systems, multimedia broadcasting systems, and other similar products. It operates at the centre frequency of 600MHz and comes with a frequency stability of ±50ppm across the operating temperature range of -20°C to 70°C and across the operating voltage range of 3.3V to 5V. Its superb frequency stability and low phase noise allows it to be used in dynamic environments where frequency drift is a major issue.

In terms of working principle, the 352VB3A600R oscillates based on an internal quartz resonator which takes the form of a tiny crystal whose natural frequency is tuned internally dependent on the supply voltage. This is why it is a voltage controlled oscillator (VCO), since its resonator is tuned by adjusting the supply voltage. This switching is accomplished through a voltage controlled amplifier (VCA) which amplifies the output voltage of the crystal according to the voltage applied to the control pins. Additionally, the oscillator is designed with trimmable frequency offset and temperature compensated frequency stability, which allows for accurate and low-noise operation.

In summary, the 353VB3A600R is a voltage controlled oscillator designed for wireless communications applications. It features a frequency stability of ±50ppm and is capable of operating across a wide temperature range from -20°C to 70°C. Its operation is based on a voltage controlled amplifier which amplifies the output voltage of the quartz resonator according to the applied voltage. It also features trimmable frequency offset and temperature compensated frequency stability.
