Title: Phil-Jae Jeon: Innovator in Clock and Data Recovery Technologies

Introduction

Phil-Jae Jeon is a prominent inventor based in Osan, South Korea. He has made significant contributions to the field of electronics, particularly in clock and data recovery technologies. With a total of 7 patents to his name, Jeon continues to push the boundaries of innovation in his field.

Latest Patents

Among his latest patents is a clock switch device and system-on-chip that includes a control circuit and a tri-state buffer. This clock switch device is designed to deactivate an output enable signal when the frequency of a clock signal varies, while activating the output enable signal when the frequency remains constant. The tri-state buffer plays a crucial role by maintaining an output electrode at a high impedance state when the output enable signal is deactivated. When activated, it buffers the clock signal and outputs the buffered clock signal as an output clock signal.

Another notable patent is the clock and data recovery circuit and method that does not rely on a reference clock. This innovative circuit includes a clock generation unit, a mirror delay unit, a preamble phase detection unit, and a sampling unit. The clock generation unit generates a clock signal that locks its phase to that of the data signal inputted. The mirror delay unit outputs delayed preamble signals based on the preamble signal during the preamble period, while the preamble phase detection unit provides a charge pump with a preamble phase detection signal that contains information on the phase difference between the preamble signal and the clock signal. The sampling unit then extracts data from the data signal by sampling it with the clock signal.
