Among them, the SIT3808AC-D2-33NH-7.030000T oscillator is a great example of oscillator technology and its application field and working principle will be discussed in this article.

Application Field

The SIT3808AC-D2-33NH-7.030000T oscillator is specifically designed for digital systems in automotive subsystems applications. It utilizes a micropower voltage-controlled oscillator (VCO) design to generate an accurate and repeatable frequency with no external components and minimal power consumption. With a wide operating temperature range from -40°C to +85°C, it is suitable for harsh conditions and long-term reliable operation in automotive environments. Furthermore, it offers excellent jitter and phase noise performance and dynamic supply current as low as 15mA from a 3.3V supply voltage.

Working Principle

The core of the SIT3808AC-D2-33NH-7.030000T oscillator is a micropower VCO architecture, which can provide an accurate and repeatable frequency without any external components. This is accomplished by using a clock generator, which receives an input voltage and produces a regular output signal across its outputs. The frequency of the output signal is determined by the frequency of the input voltage, and can be adjusted by varying the input voltage. The generated frequency is then integrated from the outputs of the clock generator back into the input voltage, allowing for a precise frequency control over a wide range.

Besides, the SIT3808AC-D2-33NH-7.030000T oscillator also features a unique frequency control circuit, allowing it to adjust the frequency by changing the key parameter of voltage or temperature. This circuit can be programmed to generate the optimal frequency for different applications while ensuring lower power consumption. In order to protect the oscillator from external noise, a built-in EMI filter is used to reduce the amount of interference.
