Abstract
A physical layer transceiver for a wireline communications system includes a receive path for communicating signals received from the medium to a functional circuit, a transmit path for communicating signals received from the functional circuit onto the medium, and echo cancellation circuitry for cancelling from the receive path echoes of signals transmitted on the transmit path. The echo cancellation circuitry includes a plurality of high-dynamic-range filter segments, a plurality of low-dynamic-range filter segments, and control circuitry configured to detect on the receive path the echoes of the signals transmitted on the transmit path, classify each echo signal as having a low dynamic range or a high dynamic range, and deploy a high-dynamic-range segment to a location of an echo signal having a high dynamic range, and deploy a low-dynamic-range segment to a location of an echo signal having a low dynamic range.
