Oscillators: SIT1602BI-71-18N-4.000000E

Oscillators are electrical components that generate a periodic pulse or other waveform that can be used as a timing reference. This type of circuit is used in numerous applications, such as timers, clocks, and radios, and requires no external synchronization. Many different types of oscillators exist, including voltage-controlled oscillators (VCOs), quartz crystal oscillators, and MEMS oscillators, among others.The SIT1602BI-71-18N-4.000000E oscillator from SiTime Corporation is a low-noise discreet oscillator designed to operate between 4.000000MHz to 25MHz. It is constructed using a Silicon MEMS structural layer along with ceramic housing, providing minimal thermal stress and a wide operating temperature range from -40°C to +125°C (Industrial Plus grade). The SIT1602BI-71-18N-4.000000E is part of SiTime’s Low Power MEMS oscillator family, offering a small package size and low current consumption of only 10µA. These features are critical for applications such as wearable technologies, connected home and specialized medical equipment, where low power is essential. Additionally, the oscillator has a maximum frequency tolerance of ±50ppm and is shock-resistant, providing a highly reliable and stable timing reference. The device is ideally suited for timing-critical operations in applications such as industrial controllers, smart grid and home automation. It can also be used in other embedded applications requiring precise synchronization and timing accuracy and stability, such as wireless communication devices, satellite communication systems and military equipment.The SIT1602BI-71-18N-4.000000E’s working principle is based on a silicon-MEMS resonator. This structure is composed of four layers – the first layer is the sintered silicon silicon cap and the others are a pair of silicon frame layers and a support layer. The resonator expands and contracts depending on temperature changes. As the temperature changes the resonator layers move, changing the vibrational characteristics of the device, which translate into frequency changes. This frequency change is kept within a tightly controlled range by measurements taken on the resonance profile and by outputting a feedback control voltage. The silicon-MEMS resonator also allows the oscillator to be shock-resistant and provides greater stability across a wide operating temperature range.The SIT1602BI-71-18N-4.000000E is designed to simplify and accelerate the development of products requiring low-noise, accurate and reliable timing sources. This MEMS oscillator is an ideal solution for applications that require extreme temperature ranges and tight timings. In applications such as wearable technologies and connected home infrastructure, the low power consumption and small package size of this oscillator make it an attractive choice. The high accuracy and timing stability of this oscillator also make it an ideal solution for timing-critical operations in industrial controllers and smart grids.
