Abstract
A system provides for a serial transmitter with multiplexing and driving functionality that is combined into a single stage to increase the overall speed of the serial transmitter. The single stage includes a dynamic impedance that is configured in parallel with a multiplexing driver to reduce the input capacitance and set the correct output impedance. The single stage can be implemented as a stacked or cross-coupled XOR logic circuit or a stacked or cross-coupled multiplexer ('mux') as the multiplexing driver. In an embodiment where a mux is used as the multiplexing driver, a clock can be injected into the mux driver to overcome inter-symbol interference.
