Patent number: 9344267Abstract: A data receiver includes a serial-data processing module, a null-frequency detecting unit, a data checking unit, a status control unit and a timeout checking unit. The serial-data processing module receives serial data, generates an operation clock, parallel data and required data, and determines whether the operation clock is correct for accordingly generating a first result. The null-frequency detecting unit receives the operation clock and determines whether the operation clock is locked or null for accordingly generating a second result. The data checking unit is enabled according to the first result and determines whether checking data of the required data is correct for accordingly generating a third result. The status control unit outputs a frequency-locked signal and changes the signal state of the frequency-locked signal according to the first to third results. The enabled timeout checking unit resets the serial-data processing module according to the signal state of the frequency-locked signal.Type: GrantFiled: September 16, 2014Date of Patent: May 17, 2016Assignee: AU OPTRONICS CORP.Inventors: Wei-Jyun Chen, Chun-Fan Chung, Chih-Fu Yang
