Adaptive backchannel equalization |
摘要 |
Techniques for adaptive backchannel equalization. A total equalization value is determined over a preselected training period. A total balance equalization value is determined over the preselected training period. A transmitter equalization coefficient is determined based on the total equalization value and the total balance equalization value. Data is transmitted over a serial link using the transmitter equalization coefficient. |

1. At least one non-transitory machine accessible storage medium having code stored thereon, the code when executed on a machine, causes the machine to:
determine a continuous time linear equalizer (CTLE) peak setting of a receiver, wherein the receiver is coupled to a transmitter by a serial link; and transmit data over the serial link based on the transmitter equalization coefficient and the CTLE peak setting, wherein determining the continuous time linear equalizer (CTLE) peak setting comprises determining a continuous time linear equalizer (CTLE) peak value change by:
increasing the CTLE peak value if a first decision feedback equalizer (DFE) tap exceeds a first preselected percentage of maximum capacity; anddecreasing the CTLE peak value if a second DFE tap has an opposite magnitude as the first DFE tap and exceeds a second preselected percentage of the first DFE first tap magnitude. |
