Abstract

Data transmitter embodiments are provided which are particularly useful as interface devices for accurate and reliable transmittal of data from high-speed data system devices such as analog-to-digital converters. Transmitter embodiments have been found to provide excellent fidelity of data transfer at high data rates (e.g., 4 gigabits/second) while consuming only a portion of the power of many conventional transmitters and requiring only a portion of the layout area of these transmitters. Transmitter embodiments provide effective control of transmitter parameters such as matched impedances, data symmetry, common-mode level, data eye and current drain.
