ABSTRACT:
A phase comparison process in a timing recovery process for high-speed data communication defines a data window and compares the phase of a clock in the window with the phase of an edge of data so as to realize a parallel process, wherein the phase comparison and the process of determining whether a data edge lies within the window are performed in parallel to each other, and the phase comparison result is output only if the data edge lies within the window. With this configuration, it is possible to perform an accurate phase comparison process with no errors without requiring high-precision delay circuits.
