PL620-21DC Working Principles

The PL620-21DC combines multiple digital circuits to efficiently control high-speed clock rates and phase-lock loops (PLLs). This allows the device to generate a wide range of digital signals with low jitter and excellent power consumption.

The device uses a digital phase-frequency detector (PFD) to compare the frequency of an incoming reference clock with the frequency of an internal feedback counter, which is controlled by a programmable divider. The resulting frequency error is then used to adjust the internal Programmable Logic Array (PLA), which generates the desired output clocks.

The PL620-21DC also integrates a variety of filters and programmable control logic, allowing designers to specify and customize the PLLs to their specific applications.

Conclusion

The PL620-21DC is a fully integrated ASIC that provides high-speed clock generators and PLLs for a wide range of applications. The device combines excellent performance, versatility and cost-effectiveness, enabling designers to develop products that meet the requirements of next-generation high-speed applications.
