The HD-SDI (High Definition Serial Digital Interface) Retimer Circuit is used in full-speed (1.485 Gb/s) HDTV bit stream switching and distribution systems. HD-SDI  contains a monolithic Clock Recovery Unit (CRU), a lock detect feature and a port bypass circuit. The CRU may be used alone to implement a general purpose repeater needed for applications where a re-timed and buffered signal is required. The Data Retimer performs the function of a port bypass circuit followed by a clock and data retiming Phase Locked Loop (CDR). The CDR re-times incoming serial data, detects whether a valid signal is present and outputs a low jitter serial data stream.
