Abstract:
A loss of lock condition of a clock signal (25) recovered from a received data stream can be detected by examining conventionally available information (25, 26) indicative of a rate of change of an interpolation ratio according to which first and second phases of a local reference clock signal are combined to form the recovered clock signal.
