Oscillators are electronic components used to generate a repetitive signal. They are widely used in nearly every electronic equipment for providing timing signals, reducing jitter, and synchronizing data transfer. In this article, we will describe the application field and working principle of the SIT1602BI-12-33E-28.636300E oscillator.

The SIT1602BI-12-33E-28.636300E is a low-power quartz Crystal Microbalance (QMB) oscillator. It is a highly stable frequency source with low jitter. The oscillator is designed to be used in applications like Bluetooth and Wi-Fi, interfaces, networking equipment, and medical electronics. It features a frequency range of 1 to 200MHz and a guaranteed stability of ±50ppm over the temperature range of -20°C to 70°C.

The working principle of this oscillator is based on the quartz crystal resonator. Quartz crystals have the ability to generate a very regular sine wave when subjected to an AC voltage. The voltage causes the crystal to vibrate at a specific frequency, which is determined by its physical characteristics. The quartz crystal microbalance (QMB) oscillator utilizes a quartz crystal element to generate a stable frequency signal by detecting the electrical impedance change caused by the mechanical vibration of the quartz crystal. The signal is further amplified with an LC resonant circuit and can be output at a stable and predictable frequency.

The QMB oscillator also features two dedicated pins for frequency adjustment. The pins are used in conjunction with an external capacitor and resistor to adjust the frequency of the oscillator. The frequency is adjusted by controlling the amount of charge stored on the capacitor and applied to the quartz crystal\'s electrodes. The transistor oscillator circuit is designed to ensure the noise immunity and low-jitter characteristics of the oscillator.

In summary, the SIT1602BI-12-33E-28.636300E oscillator is a highly stable frequency source with low jitter, designed for low-power applications like Bluetooth and Wi-Fi, interfaces, networking equipment, and medical electronics. Its working principle lies in the ability of quartz crystals to generate a periodically recurring signal when subjected to an AC voltage. The frequency of the oscillator can be adjusted using two separate pins for the adjustment of an external capacitor and resistor. This oscillator is a perfect choice for a wide variety of applications in the electronics field.
