The SY87721LHG is a designed Clock/Timing-Application Specific product that is an advanced clock generator, phase-locked loop (PLL) and also a precise jitter attenuator – all in one integrated circuit (IC) package. This product offers a universical solution to complex systems that require reliable long-term and precise clock generation, phase-locked loops, and jitter attenuation, such as consumer and computer systems, networking systems, machine vision, aerospace and automotive applications. In a practical application, the SY87721LHG is ideally suited to fulfill the demanding requirements of precision timing and synchronization, as well as jitter attenuation over long distances.

The SY87721LHG is a single chip solution integrated with a frequency synthesizer, a programmable jitter attenuator, a programmable PLL and many other features. It offers very compact designs for various applications. The frequency synthesizer is an important part of the SY87721LHG, as it allows for dynamic, programmable clock generation. This means that the clock output can be adjusted to the desired frequency. The jitter attenuator is also very useful helping to reduce unwanted jitter caused by noise in the system.

The SY87721LHG works by having an internal frequency synthesizer, a jitter attenuator and a PLL. It detects the input clock frequency and synchronizes it with an internal replica. It is then able to make an output clock of the desired frequency, as well as a precise jitter attenuated version of the output clock. The frequency synthesizer can also be used to dynamically scale the output clock frequency. The jitter attenuator and PLL are two important features, as they help to eliminate unwanted jitter caused by noise and to synchronize the output clock with a reference clock.

In addition to these capabilities, the SY87721LHG is also able to offer various parameters for timing and synchronization. It has a wide range of available reference clock sources, including multiple external source options. It also comes with a slew rate control feature, which is useful for fast transition times. Lastly, the SY87721LHG features a DC-Level down-shifting feature which allows the user to progressively down-shift the clock output from its high DC level to a lower DC level, ensuring smooth transitions.

The SY87721LHG is a highly advanced clock generator, PLL and jitter attenuator all in one package. This product is ideal for applications requiring precision timing, synchronization and jitter attenuation, as it is able to offer a wide range of reference clock sources, as well as dynamic frequency scaling and slew rate control. The main functions of the SY87721LHG include frequency synthesis, jitter attenuation, and PLL synchronization, which help to offer reliable long-term and precise clock generation, phase-locked loops, and jitterattenuation over long distances.
