Abstract
A machine-readable medium thereupon stored a design structure; the design structure includes a receiver for a data communications system. The receiver includes a data path for receiving a data signal from a data channel, the data path comprising an automatic gain control (AGC) loop; and, a signal detector for generating a data valid signal indicative of the validity of the data signal in response to detection of the data signal on the channel exceeding a threshold and in dependence upon gain information from the AGC loop in the data path.

A non-transitory machine-readable medium thereupon stored a design structure, the design structure comprising a receiver for a data communications system, the receiver comprising:
- a data path for receiving a data signal from a data channel, the data path comprising an automatic gain control (AGC) loop;
- a signal detector, outside said AGC loop, the signal detector comprising a comparator for comparing the data signal to a threshold for generating a data valid signal indicative of the validity of the data signal in response to detection of the data signal on the channel exceeding the threshold and in dependence upon gain information from the AGC loop in the data path;
- and
- a variable signal source for setting the threshold in dependence upon the gain information from the data path.
A non-transitory machine-readable medium thereupon stored a design structure, the design structure comprising a data communications system, the data communication system comprising a first data processing node and a second data processing node interconnected by a data communications channel, wherein at least one of the first and second nodes comprises a receiver comprising:
- a data path for receiving a data signal from a data channel, the data path comprising an automatic gain control (AGC) loop;
- a signal detector outside said AGC loop, the signal detector comprising a comparator for comparing the data signal to a threshold for generating a data valid signal indicative of the validity of the data signal in response to detection of the data signal on the channel exceeding the threshold and in dependence upon gain information from the AGC loop in the data path;
- and
- a variable signal source for setting the threshold in dependence upon the gain information from the data path.
