  • Patent number: 11991025
    Abstract: Examples described herein include setting an equalizer tap setting and gain setting in a serializer/deserializer (SerDes). In some examples, determining an equalizer setting and gain setting occurs by causing a mean-square error cost scheme tracking to lock to an offset from a minimum of a cost of the mean-square error cost scheme without pausing error cost tracking. In some examples, the mean-square error cost scheme comprises a least mean square (LMS) scheme. In some examples, determining an equalizer setting comprises: applying increases or decreases to an equalizer setting, and an increase to an equalizer setting can be a different amount than an amount of decrease to an equalizer setting.

  • Patent number: 11973624
    Abstract: Examples described herein relate to link training between network connected devices. In some examples, an amount to extend link training is determined. The amount to extend link training can be determined by: receiving, by a receiver in a first device, signals over a lane from a transmitter in a second device, the signals indicating capability to extend link training time and amount to extend link training time; determining, at the first device, a link training time based on a default link training time and an amount to extend link training time; and performing link training based on the determined link training time. In some examples, the determined amount is highest common denominator of the received identified capability and transmitted indicated capability. In some examples, if the received communication indicates no ability to extend link training time, the link training time is a default link training time.
