Abstract: Methods and apparatus to compensate for post-training insertion loss variation. Receiver Physical Layer (PHY) circuitry for each receive lane in a link comprising a chain of equalizer components including a Variable Gain Amplifier (VGA). In conjunction with initial link training, the VGA gain is set based on an initial temperature. During link training, one or more of the equalizer components are adjusted to obtain link convergence, followed by transitioning to a “link up” phase under which data transmission and reception begin. While operating in the link up phase, one or more of the equalizer components are adjusted in response to changes in interconnect insertion loss to maintain operation of the link within a link margin. The method may be implemented in various types of links including but not limited to Ethernet, PCIe, CXL, and UPI links.
