FREQUENCY DETECTOR AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240275390 titled 'FREQUENCY DETECTOR AND OPERATING METHOD THEREOF
The abstract describes a frequency detector that utilizes multiple flip-flops and a delay cell to analyze the frequency difference between a data signal and a clock signal.
- The frequency detector includes three flip-flops: one sampling the clock signal, one sampling a delayed-phase component of the clock signal or the data signal, and one generating a signal representing the frequency difference between the data rate and the clock frequency.
- A delay cell is used to generate the delayed-phase component of the clock signal or the data signal with a delay amount set to a value smaller than about 0.25 UI.
- The detector is designed to accurately detect and analyze frequency variations in signals, providing valuable information for signal processing and communication systems.
