    Patent number: 8713238
    Abstract: A communication circuit includes a communication port, a receiver an aligner, and a link recovery circuit. The communication port is configured to connect to a communication link and to disconnect from the communication link. The receiver is configured to generate, while the communication link is connected to the communication port, a serial sequence of received bits recovered from the communication link. The aligner is configured to decode a received sequence of blocks from the serial sequence of received bits. The blocks of the received sequence include data blocks and control blocks. The link recovery circuit is configured to reset the receiver in response to the blocks, in the received sequence after a first one of the control blocks and before a next one of the control blocks, numbering greater than a threshold number.
