Abstract
A transmitter includes driver slices coupled to its output. Each driver slice includes a first differential predriver that is selectively enabled and disabled by a first switch based on a control code configuration. A second differential predriver provides a first differential buffered data signal to a first group of driver slices when the second differential predriver is enabled. A second switch enables the second differential predriver when the control code is configured to enable the first differential predriver in at least one driver slice in the first group of driver slices. A third differential predriver provides a second differential buffered data signal to a second group of driver slices when the third differential predriver is enabled. A third switch enables the third differential predriver when the control code is configured to enable the first differential predriver in at least one driver slice in the second group of driver slices.
