Patent number: 11588614Abstract: A method of frequency search and error correction of clock and data recovery circuit, comprising: initializing a frequency search algorithm parameter; processing a frequency error parameter UP/DN signals according to the set algorithm parameter and starting the frequency search, in which, the algorithm accordingly counts the UP/DN signals. When a phase error signal transition occurs, a transition parameter JUMP is accumulated by 1, and an accumulation parameter SUM is obtained and is further judged that whether a frequency search result is to be output. Number of repeating times of verification and threshold parameters are set, accordingly a reset DCRL value is obtained to verifies a frequency locking result and outputs the result.Type: GrantFiled: September 15, 2022Date of Patent: February 21, 2023Assignee: EVERPRO TECHNOLOGIES COMP ANY LIMITEDInventors: Jinfeng Tian, Yan Li
