Introduction to Oscillators

An oscillator is an electronic circuit used to produce a repetitive electronic signal, usually a sine wave or a square wave. It can be used to generate a wide range of frequencies, from very low frequency (fractions of a Hz) to very high frequency (several GHz). Oscillators are typically used either as a time-independent clock generator, or as a signal generator to send out signals to other circuits, such as a digital-to-analog converter (DAC), or as a voltage-controlled oscillator (VCO) to modulate the amplitude or frequency of another signal. Oscillators are widely used in electronic devices, ranging from basic clock timing circuits to complex processors and communications systems. They are also essential components in many digital and radio communication systems, including wireless networks, cellular phones, and radar systems.

DSC1001BI2-020.0016T Application and Working Principle

The DSC1001BI2-020.0016T is a dual SMD Synthesized Oscillator produced by Global Mixed Mode. It comes in a miniature 6-pin package that makes it ideal for portable and miniature electronic devices. The device is internally temperature compensated over the standard operating temperature range of -20C to 65C.The DSC1001BI2-020.0016T is a crystal oscillator with an integrated frequency synthesizer controlled by a three-wire serial interface. It helps reduce the number of external components and pins needed to generate a system clock signal. The device features a low phase-noise that meets or exceeds industry standards, as well as jitter performance. It supports 0 to 5-V logic levels and covers the wide continuously variable frequency range of 1 - 200 MHz.The device incorporates an internal voltage-controlled oscillator (VCO) with an external loop filter, along with a phase-locked loop (PLL) and a frequency reference divider. The clock output signal is generated by a digital frequency synthesizer, of which the PLL can be programmed with a 3-wire serial interface. The frequency reference divider is used to divide the fundamental frequency of the VCO to the desired output frequency. The PLL locks the VCO to this reference frequency to minimize the rate of frequency wander.

Conclusion

The DSC1001BI2-020.0016T is an ideal synthesized oscillator for use in small, low-power applications. It is an efficient, low-noise device that offers a wide-range of frequency outputs and is simple to program and control with the three-wire serial interface. The device is perfect for use in any application that requires a high-precision clock, such as precision timing circuits, wireless networks, and cellular phone systems.
