This oscillator is a cost-effective solution that offers versatility in oscillator design and reliable performance. In this article, we will discuss the application fields and working principle of SIT8009BIF71-30S oscillator in detail.

The SIT8009BIF71-30S oscillator is a PLL-based programmable oscillator with a two-stage frequency synthesizer. This oscillator is available in 32.768 kHz to 604 KHz frequency range with 200 Hz frequency step size, and a stable frequency accuracy of +/- 20ppm over the industrial temperature range. The frequency accuracy of this oscillator ranges from 5 – 20 ppm depending on the process and chip temperature. The SIT8009BIF71-30S oscillator comes in a 3.2 x 2.5mm package and is optimized to operate at frequencies below 500 kHz.

The SIT8009BIF71-30S oscillator can be used in many consumer and automotive applications requiring high repeatability, low power consumption, and precise frequency control. These oscillators are ideal for systems that require precise frequency and timing control, such as automotive systems, consumer electronics, and networking applications. This oscillator is also commonly used in automotive remote keyless entry systems, car navigation systems, air Bag systems, body electronics, and timing of high-speed data buses.

The working principle of the SIT8009BIF71-30S oscillator is straightforward. This oscillator utilizes a phase-locked loop (PLL) to control the frequency of its output signal. The PLL consists of a phase detector, a charge pump, and a voltage-controlled oscillator (VCO). The phase detector compares the input signal with the VCO\'s output signal, and the resulting difference is used to control the VCO\'s frequency. The charge pump increases or decreases the VCO voltage, and the resulting frequency change is accurately locked to the incoming signal. In addition, the SIT8009BIF71-30S oscillator features an adjustable divider and output driver, allowing the user to adjust the output frequency as desired.

The SIT8009BIF71-30S oscillator is a versatile and cost-effective solution for a wide range of consumer and automotive applications. Its low power consumption and precise frequency control make it an ideal choice for systems that require high repeatability and accurate timekeeping. The PLL-based design also ensures a stable frequency accuracy, as well as adjustable output frequency, making this oscillator suitable for a variety of applications. With its small form factor, it is a perfect solution for automotive systems, body electronics, and high-speed data buses. With its superior performance and broad application fields, SIT8009BIF71-30S is sure to find its place in many upcoming products.
