The CDC950DGGR is a clock generator designed to deliver high-quality clock and timing signals. It is used in a broad range of applications such as TV, DVD and sound systems, electronic instrumentation, embedded controllers, communications and automotive systems.

CDC950DGGR works by providing clock signals with a minimum voltage swing over a wide frequency range. It reduces noise and crosstalk on the output. In addition, the CDC950DGGR have the ability to simultaneously generate multiple clock outputs from a single reference input. It can be used to interface to any systems requiring an accurate clock and timing source.

The CDC950DGGR is typically used for generating clock signals in radio frequency (RF) and timing applications. It also produces reference clock signals for communications and networking systems. It is specially designed for applications where accurate frequency synthesis, high performance and wide ranging output frequencies are needed.

The CDC950DGGR consists of a main high-speed oscillator module and two peripheral modules comprising of of two low-speed oscillators and a divide-by-two frequency divider. The main oscillator accepts a user-defined reference clock as an input and produces a stable clock output. The oscillator module consists of an oscillator core, an analogue phase-locked loop (PLL) and an input buffer. It allows two different reference clock sources, one of which can be used to program the PLL.

The two peripheral modules are used for the generation of different clock signals from the reference. The low-speed oscillators consist of a programmable VCO components and a set of dividers. The output of the oscillator is then further divided by the frequency divider providing the different clock outputs. This feature provides better accuracy and stability in the output clocks.

The CDC950DGGR has a wide operating frequency range from 0MHz to 120MHz. It also has a low jitter performance, allowing for reliable communication over varying frequencies. The PLL can be used to maintain the phase and frequency accuracy over long periods of time without requiring an extra source of source clock frequency. In addition, the PLL can accommodate process variations, frequency drift and temperature changes.

Overall, the CDC950DGGR is a reliable and versatile clock generator that can be used for a wide range of applications. By providing high-quality clock signals over a wide frequency range, it is suitable for any systems requiring an accurate clock and timing source. It is highly flexible, allowing for different clock frequencies and phase relationships to be generated from a single clock reference.
