Patent number: 12155390Abstract: A clock recovery circuit comprises an input node receiving a data signal having a data rate, and a digital oscillator producing a local clock signal with a frequency higher than the data rate. A counter clocked by the local clock signal has its count value sampled and reset at the rising and falling edges of the data signal, and a storage block coupled to the counter stores a count value that is updated in response to the current sampled count value of the counter lying in an update range between lower and upper bounds. A threshold value set is produced as a function of the updated count value stored in the storage block. Sampling circuitry receives and samples the data signal, and provides a sampled version of the data signal in response to the count value of the counter reaching any of the threshold values.Type: GrantFiled: October 17, 2022Date of Patent: November 26, 2024Assignee: STMicroelectronics S.r.l.Inventor: David Vincenzoni
