Abstract
This disclosure provides methods, devices, and systems for wireline communications. The present implementations more specifically relate to line driver circuits that support differential and single-ended signaling. In some aspects, a line driver circuit may include a pair of transmit (TX) digital-to-analog converters (DACs) and a 'mock' TX DAC. When operating in a differential mode, the line driver circuit uses both TX DACs to drive a primary data signal and a complementary data signal onto a differential transmission line. When operating in a single-ended mode, the line driver circuit uses only one of the TX DACs to drive the primary data signal onto a single-ended transmission line and converts the complementary data signal to a mock echo signal via the mock TX DAC, where the mock echo signal mimics an echo of the complementary data signal. The mock echo signal may cancel echoes associated with the primary data signal.
