Oscillators – DSC1033CC1-100.0000T application field and working principle

An oscillator refers to a circuit that autonomously produces vibrations or oscillations when powered by a source of direct current (DC) power. Oscillators are among one of the most widely used and versatile components found in a variety of industrial, communications, automotive, and consumer electronics applications. The oscillators provide controlled timing and frequency references for many electronic devices, so it is important to understand the basics of oscillators and their various applications in order to make proper decisions when selecting the best oscillators for specific applications.The DSC1033CC1-100.0000T is a digitally controlled oscillator (DCO) designed to deliver optimal performance and low power consumption in a wide variety of timing and frequency reference applications. It is an ultra-low jitter, wide range and low power DCO that provides an output frequency range of 30kHz to 100MHz and stable performance at a low power consumption of only 6.5mA.This oscillator is typically found in high speed communications, video, audio, computer networking, and consumer electronics applications where pulse width, rise and fall times, and frequency accuracy requirements are very important. Its ultra-low jitter and wide frequency range enable designers to provide optimal performance to their products.The DSC1033CC1-100.0000T features a DC voltage control interface which is used to adjust the output frequency and phase of the oscillator. It also has an output enable/disable pin which can be used to turn off the oscillator when not in use, thus reducing power consumption. In addition, it has a selectable current consumption feature that allows designers to adjust the current consumption of the oscillator for lower power consumption at the expense of output swing or power supply voltage range.The heart of the DSC1033CC1-100.0000T is a digitally controlled multi-modulus frequency synthesis system, which provides an output frequency range of 30kHz to 100MHz. This is achieved by combining a wide range of frequencies and adjusting them in a set order to achieve the desired output frequency. The output frequency is set by inputting a digital number to the synthesizer. The accuracy of the output frequency can be precisely controlled by accurately programming the digital number to the synthesizer.The DSC1033CC1-100.0000T utilizes a phase locked loop (PLL) which is used to precisely phase lock the output frequency to the input reference frequency. The loop filter of the PLL is an analog RC circuit, whose corner frequency can be precisely adjusted by programming the current consumption of the oscillator. The phase detector of the PLL utilizes the phase error voltage of the loop filter to detect the phase difference between the input reference clock and the output frequency, and feeds the phase error voltage to a digital phase locked loop (DPLL) which further adjusts the output frequency to precisely match the input reference frequency.The DSC1033CC1-100.0000T also features a jitter cleaning functionality that enables designers to reduce the amount of jitter present in the output waveform at any given frequency. This is done by passing the output frequency through a jitter cleaning digital filter, which enhances the stability and accuracy of the output frequency.The DSC1033CC1-100.0000T is a versatile oscillator with excellent performance, low power consumption, and wide frequency range, making it an ideal choice for many digital communications, computer, consumer electronics, and audio/video applications. Its wide range and low power consumption make it well-suited for applications that require accuracy and reliability such as automotive, medical, and industrial applications. This oscillator also has the added benefit of being easy to configure and customize for specific applications, making it a popular choice for many designers.
