Oscillators

Oscillators are electronic components that generate patterns or waveforms in the form of an electrical signal. They are used in a variety of applications, from providing clocking or timing signals for digital logic circuits to supplying the output signal for radio receivers and transmitters. Oscillators can also be used in analog circuitry to provide sine wave signals for power supplies and various signal conditioning applications. The DSC1121BI2-012.2880T is an R/C Oscillator specifically designed for use in personal computers and other electronic applications.

DSC1121BI2-012.2880T application field and working principle

The DSC1121BI2-012.2880T R/C Oscillator is designed to provide a precision timing signal in a wide range of digital and analog applications. This oscillator is well suited for use in PC systems where precise timing signals are generated for system control, data acquisition, and other purposes. It is especially designed for high performance applications, such as multimedia, high speed microprocessors, and power management.

The DSC1121BI2-012.2880T works by generating a precise frequency output using a quartz crystal and a transistor-based frequency feedback circuit. This type of oscillator uses a combination of hysteresis and negative feedback to maintain accuracy over temperature, voltage, and process variation. The oscillator frequency is set by the quartz crystal and is further adjusted by the feedback circuit. The feedback transistors control the input current to the quartz crystal, which in turn determines the output frequency of the oscillator. This makes the oscillator very precise and stable over temperature and voltage variations.

The DSC1121BI2-012.2880T is designed to operate over a wide supply voltage range of 3.0 V to 5.5 V. It also has a wide supply current range of 15 mA to 25 mA, which makes it suitable for low power applications as well. The maximum frequency it can generate is 200 MHz with a stability of ±30 ppb and a jitter of 150 ps. The frequency stability of the DSC1121BI2-012.2880T is excellent – up to ±100 ppb over a -40°C to 85°C temperature range.
