Oscillators

Oscillators refer to circuits or components that can generate periodic signals based on the principle of frequency stability. The basic components of oscillator include inductance, capacitance and resistance, or other processing components such as operational amplifiers and transistors. Oscillator can be divided into two categories according to the type of waveform it generates. The first is an amplitude-modulated oscillator, which is used to generate a signal with a small amplitude, such as resistance frequency welder, sound amplifier and so on. The other is sine wave oscillator, which is mainly used in high-frequency communication system and automatic control system.

SIT1602BC-13-28E-6.000000D is a new type of full-board programmable oscillator. Its overall size is 14.0*9.2*2.5mm. It uses MEMS (Micro Electro-Mechanical System) technology to realize high stability and wide temperature range performance. It can meet Frequency range of 6KHZ~100MHZ frequency output; Frequency stability of ±30ppm@25℃; The maximum frequency deviation of ±10ppm@-40~+85℃; aging rate of ±5ppm/year. Therefore, the SIT1602BC-13-28E-6.000000D can be widely used in many fields such as GPS modules, base stations, wireless modules and other IoT related fields.

As for working principle of SIT1602BC-13-28E-6.000000D, the function of oscillator is mainly to realize the frequency pumping stability. This oscillator uses the MEMS resonator as its frequency source. At the core of the MEMS resonator is a tiny suspended metal structure managed by electrostatic forces. It consists of a mechanical framework system and electrodes attached to the framework, as well as small movable part of mass, and a proof mass anchored to it. When an alternating current is applied, the proof mass will move according to the electrostatic force, so that the resonance frequency is generated, and the oscillation is realized. Under the on-board oscillator module, the frequency generated by the MEMS resonator is amplified and output by a set of frequency pumping circuit.

In conclusion, SIT1602BC-13-28E-6.000000D is a programmable oscillator that uses MEMS technology to ensure high stability and wide temperature range performance, and is widely used in various fields. Its working principle is to realize oscillation via MEMS resonator and frequency pumping circuit.
