DSC1001DI5-004.0000T is a member of the oscillator family which consists of PLLs (Phase-Locked Loops), voltage controlled oscillators, crystal oscillators, and quartz crystal oscillators, among other types.

Application Field of DSC1001DI5-004.0000T

The DSC1001DI5-004.0000T oscillator is a TROV-type oscillator that is typically used in the mobile radio frequency (RF) market of cellular telecommunications. It is also used in cable/satellite applications, consumer electronics, and industrial/medical/military applications. It is designed to provide a low jitter clock signal for SSCG (Spread Spectrum Clock Generation) when used in synchronization with a mobile radio transceiver.

Working Principle of DSC1001DI5-004.0000T

The oscillator operates on a PFD (phase-frequency detector) and loop filter-based architecture. It employs a high-speed and low-power CMOS technology. The PLL design of the oscillator uses a negative feedback loop that consists of two loops, the reference oscillator loop and the VCO loop, to generate a low jitter clock signal. The reference oscillator loop is responsible for generating a reference clock signal and the VCO loop is responsible for tracking the output frequency of the reference oscillator. The PLL also contains a frequency-doubling circuit, which is used to convert the reference clock frequency to the twice the frequency for the VCO output.

On the other hand, the PFD itself is a monolithic integrated circuit containing two discriminators, which are used to compare the phase and frequency difference between the reference oscillator signal and the output of theVCO. This information is then fed back to the loop filter, allowing the PLL to adjust the output frequency of the VCO so that it tracks the reference oscillator. The implementation of a PFD facilitates the operation of the oscillator, making it more stable and efficient.

Apart from the PFD, the oscillator also contains a low-power CMOS divider, which is used to divide the output of the VCO into multiple frequency ranges. The divider is used to reduce the frequency of the clock signal and to generate angular frequency components for different applications.

In conclusion, the DSC1001DI5-004.0000T oscillator is one of the most advanced oscillators available in the market. It has a highly efficient PLL design and is capable of providing low jitter clock signals for complex applications. Its flexible frequency dividers make it suitable for use in a wide range of applications and its low power consumption makes it ideal for long-term use.
