Abstract
An example apparatus includes a line driver and an interface circuit. The line driver has a plurality of source-series terminated (SST) driver segments including switching circuitry to selectively switch among at least three voltage-reference levels to drive an output node, common to each of the SST driver segments, in response to received digital signals by switching at a rate that is faster than a baud rate characterizing the received digital signals. The interface circuit drives a transmission link, in response to a drive signal at the output node, with an analog signal representing an oversampling of the received digital signals.
