  • Patent number: 11955166
    Abstract: Embodiments of the disclosure include signal processing methods to precondition signals for transmission on a high speed bus. A preconditioning circuit is configured to receive a serialized data signal at an input node and to precondition the serialized output data signal to provide a preconditioned output signal at an output node. The pre-conditioning circuit may include a feedback circuit coupled between the input node and the output node that is configured to independently control both of a propagation delay between the output node and the input node and a magnitude of emphasis/de-emphasis applied to a signal at the output node for provision to the input node.
