SIT8008BIR7-18N

Programmable oscillators are a type of integrated circuit (IC) in which the frequency of oscillation is adjustable by a small set of external components. The SIT8008BIR7-18N is a programmable oscillator that provides excellent temperature stability, tight tolerance, and high reliability. The oscillator consists of a temperature-stable quartz crystal resonator and an oscillator circuit with integrated capacitors and resistors, which can be used to adjust the frequency of the oscillator.

The SIT8008BIR7-18N programmable oscillator is designed to operate at a number of frequencies between 4.000MHz and 18.00MHz. It is available in a 1.6 x 2.5mm 8-pin LGA package, with a maximum operating temperature of 85°C. This quartz crystal resonator is highly reliable and provides excellent temperature stability and tight tolerance for frequency adjustments.

The SIT8008BIR7-18N is well suited for applications that require tight frequency control in a variety of conditions and environments. It can be used in a wide range of applications, from automotive safety and navigation systems to medical equipment and industrial measurement systems. This oscillator is also suitable for timing applications such as pulse-width modulation (PWM) controllers, clock and data recovery circuits, and more.

The working principle of the SIT8008BIR7-18N programmable oscillator is simple. The quartz crystal resonator acts like a voltage-controlled oscillator (VCO) circuit, where the frequency of oscillation is dependent on the applied voltage. When a voltage is applied to the quartz crystal, it vibrates at a frequency determined by the crystal. The frequency of vibration can be adjusted by changing the capacitance of the oscillator circuit, which is accomplished by adding external components to the oscillator circuit.

The frequency of the oscillator can be precisely controlled by using a combination of external capacitors and resistors. The capacitors and resistors can be adjusted to tune the frequency and accurately control the oscillator’s output. The external components can also be used to adjust the duty cycle of the oscillator, which is important in applications such as PWM controllers.

The SIT8008BIR7-18N programmable oscillator is an excellent choice for applications that require reliable frequency stability and wide temperature range operation. With its tight tolerance, high reliability and multiple frequency options, this is the ideal solution for automotive, industrial and medical applications.
