Title: Kazuaki Tanida: Innovator in Data Recovery Circuits

Introduction

Kazuaki Tanida is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of data recovery circuits, holding two patents that showcase his innovative approach to technology. His work focuses on enhancing the accuracy and efficiency of data transfer between different clock domains.

Latest Patents

Tanida's latest patents include a data/clock recovery circuit designed for recovering data and clock signals with high accuracy. This circuit utilizes an edge detector, a clock selection signal generating circuit, a clock selection circuit, and a synchronizing circuit. The edge detector generates edge position information using a receiver output as a clock signal. The clock selection signal generating circuit produces a clock selection signal in response to this edge position information. The clock selection circuit then selects a recovered clock signal from a group of clock signals based on the generated clock selection signal. Finally, the synchronizing circuit synchronizes the receiver output using the recovered clock signal, outputting it as a synchronized data signal.

Another patent focuses on a data transfer device that facilitates data transfer between blocks operating in different clock domains. In this device, the number of pulses of a clock signal, referred to as CLK-A, is circularly counted within a range from '0' to '7', producing count signals that indicate the count values. A clock signal, CLK-B, with a frequency lower than that of CLK-A, is generated from count signals of “3” and “7”. This allows for synchronized data transfer between a high-speed operating block and a low-speed operating block, ensuring efficient communication.
