Oscillators: 353VB3I14CT Application Field and working Principle

Oscillators are important components in many electronic systems, controlling the timing and frequency of various signals, from microcontrollers that power home appliances to telecommunication systems for the military. The 353VB3I14CT is a high-performance oscillator designed to be one of the most reliable and accurate solutions on the market. It is a cost-effective, ultra-stable oscillator for demanding applications.

The 353VB3I14CT is designed to provide a reliable, accurate and stable frequency output. The oscillator features a wide operating temperature range of -20°C to +85°C, and offers a fast start-up time, typically 4ms from power-on. It is also designed to achieve extremely low phase jitter at 2.5ps TYP (12KHz~20MHz). A scratchpad register is available for setting user-defined frequency parameters, allowing the oscillator to be tuned precisely for current output requirements. The device is available in 5V and 3.3V CMOS outputs. Furthermore, the oscillator is also offered in four package sizes of 5x3.2mm, 5x3.2mm LCC, 5.0x5.0mm, and 7.0x5.0mm.

Application Field

The 353VB3I14CT is mainly used as a reference clock to help eliminate reflections and reduce system cost in communication and industrial applications. The oscillator’s synergy of high precision and ultra-low phase jitter, combined with a wide operating temperature range, makes it suitable for a wide range of applications, including high-speed communications systems, base stations, satellite communications systems, GPS, SSD etc.

Working Principle

This oscillator works on a quartz crystal oscillator circuitry that controls the frequency of an output signal based on a quartz crystal resonator. It utilizes the piezoelectric effect of quartz crystals to convert electrical energy into mechanical energy. The electrical signals sent to the quartz crystal are then converted to mechanical vibrations, which allows the quartz to repeat at regular intervals. This repetition of regulated pulses at very exact frequency intervals is converted back to an electrical signal. The frequency of the output is determined by the combination of the crystal’s physical construction as well as the type of circuitry the signal is passed through.

The quartz resonator in the 353VB3I14CT is encased in a package, which provides a protective coating for the resonator. The quartz crystal is held rigidly between two electrodes, with an electrical ground connected to the package. The quartz oscillates in response to the electrical signals sent to it from an input IC. It then creates a resonance that is applied to the circuit in a feedback loop for precise timing.

The resonator\'s design ensures the frequency will remain very stable over a variety of environmental changes, while the quartz crystal can be accurately tuned to the desired frequency. Combined with advanced semiconductor technology and advanced fabrication processes, the 353VB3I14CT offers an optimal solution for customers requiring reliable, accurate and stable frequency output.
