Patent number: 11728832Abstract: An interface circuitry includes an interface, a transmitter module and a receiver module. The transmitter module includes an input stage, a driving circuit and a regulator circuit. The input stage is powered by a regulated voltage and configured to receive an input signal and generate a first output signal and a second output signal. The driving circuit is configured to drive the interface according to the first output signal and the second output signal and to provide a first data signal, a second data signal and a driving signal. The regulator circuit is coupled between the input stage and the driving circuit, and configured to provide the supply voltage according to the driving current.Type: GrantFiled: September 24, 2020Date of Patent: August 15, 2023Assignee: ARTILUX, INC.Inventor: Shao-Hung Lin

Patent number: 11303283Abstract: Introduced here are techniques for implementing a clock and data recovery circuit with improved tendencies, such a pull up and/or pull down tendencies. In various embodiments, the CDR circuit includes a phase detector that receives an input signal and a output reference clock signal. The phase detector then outputs two signals to charge pump. The output from the charge pump drives an oscillator control voltage up or down depending the current from the charge pump. A lock detector detects whether a lock has occurred by comparing the oscillator control voltage to a predetermined threshold voltage. A lock can occur when the circuit has settled into a frequency substantially near the frequency of the input signal and the oscillator control voltage is substantially near the threshold voltage. A controller circuit can control a sweeping of an available frequency range by the circuit until a lock occurs.Type: GrantFiled: January 7, 2021Date of Patent: April 12, 2022Assignee: Artilux, Inc.Inventor: Shao-Hung Lin
