Abstract
A method and system are provided for drift compensation, providing a live data approach to sampler offset calibration, such as for voltage and/or temperature (VT) drift. A serializer/deserializer (SerDes) system includes a SerDes receiver and receiver logic, the receiver logic including a forward error correction (FEC) module. A drift compensation device, or drift compensation engine, receives live error corrections from the FEC module based on FEC operations performed on live traffic passing through the SerDes receiver. A drift compensation command is provided to a data sampler in the SerDes receiver, to adjust a sampling voltage of the data sampler. When the system includes a plurality of data samplers, the drift compensation device determines the data sampler with which an error correction is associated. The drift compensation command can be sent after a threshold criterion is satisfied, such as completion of a statistics collection period, or a threshold number of corrections.
