The PL602-21TI is a device used in computer system clock management, and is part of the broader category of clock generators, phase-locked loops (PLLs), and frequency synthesizers. The primary purpose of these devices is to maintain an accurate frequency and phase information between different clocks in a computer system by providing the necessary synchronization signals.

PL602-21TI is a bidirectional PLL (phase-locked loop) used for transferring clock and data signals between different clock domains. It provides data rates between 50MHz and 1000MHz, supports a variety of heterogeneous clock sources, and is compliant with the OpenFlexibleLink (OFL) standard. The device has two integrated DLLs (delay locked loops) for data recovery and one for clock synchronization.

The working principle of the PL602-21TI involves the transfer of clock and data signals between different clock domains. In a clock domain, the PLL is the key component, setting up a feedback loop that keeps the clocks and data signals synchronized. The PLL receives the reference clock, which sets the desired frequency and phase relationships between the clocks. The PLL then uses these reference values and compares them to the actual clock and data signals to generate an error signal. This error signal is then used by the PLL to adjust the clock frequency and phase to match the reference values.

The PL602-21TI has a wide range of applications, including file and storage systems, virtual processing systems, multi-channel bus systems, and GNSS (Global Navigation Satellite System) systems. It is also used in test and measurement equipment, such as oscilloscopes, logic analyzers, and signal generators. The device is particularly suitable for applications that require high speed transfers of clock and data signals between different clock domains.

Overall, the PL602-21TI is an indispensable device for any computer system that requires efficient clock and data signal synchronization. It is an important tool for ensuring accurate and reliable connections between clocks and systems and is used in a variety of different applications. Thanks to its flexible design, the device is suitable for a wide range of applications and is capable of handling high speed data rate transfers.
