20140126678 | ALL DIGITAL BURST-MODE CLOCK AND DATA RECOVERY (CDR) - The present invention relates to a clock and data recovery (CDR) unit comprising of a bang-bang phase detector to receive data and a recovered clock from a phase selector multiplexer. The phase detector produces a late and an early comparison output. A block (digital filter) receives the late and early input and produces a multiplexer selector control signal. The phase selector multiplexer selects a clock phase as the recovered clock signal using multiplexer selector control signal. | 05-08-2014 |
