Oscillators

Oscillators are electronic circuits that generate an ongoing repetitive alternating signal, usually a sine wave. They are used in a wide variety of applications, including radio transmitters and receivers, consumer electronics, cyclocomputers and clocks, medical equipment, and mission-critical industrial systems. The SIT1602BI-81-18E-28.636300T is an oscillator designed to provide reliable, low power performance in critical applications.

Electrical Characteristics

The SIT1602BI-81-18E-28.636300T is rated at an operating voltage of 1.8V and a current draw of 5mA to 8mA. It provides a stability range of +/- 75 ppm over a temperature range of -40°C to +85°C. It is equipped with an oscillating frequency of 28.636300MHz, a supply voltage of 1.8V, and a supply current of 5mA to 8mA maximum. The insertion loss is 0.5dB, the harmonics are -30dBc (typical) minimum, and the operating temperature range is -40°C to +85°C. The oscillator size is tiny and provides a great size-to-performance ratio. The mounting package is a molded bubble.

Application

The SIT1602BI-81-18E-28.636300T is a robust oscillator that can be used in a variety of mission-critical systems. These include access control, automotive electronics, satellite communications, industrial robotics, and medical instruments. It can also be used in handheld consumer devices such as mobile phones and radios. The tiny size and low power requirements make it ideal for battery-operated devices.

Working Principle

The SIT1602BI-81-18E-28.636300T is an LC-type oscillator with a quartz crystal used as the main active element. The quartz crystal quartz crystal is composed of two plates of quartz, with the two plates held together in a vacuum chamber. An electric current is passed through the crystal, which causes it to vibrate at its resonant frequency. As the crystal vibrates, an AC signal is produced, which is then amplified and used as the oscillator output. The LC circuit is used to deliver a precise oscillation frequency to the oscillator by adjusting the frequency of the AC signal. The oscillator also uses active components such as transistors to provide gain and noise reduction.
