Abstract
Configurable voltage mode transmitter architectures are based on combinations of drive cells and parallel termination cells connected in parallel across an external load to provide configurable output characteristics. Each drive cell and parallel termination can be individually enabled, various configurations of enabled cells providing the output characteristics configurability. In some embodiments, dedicated or configured pre-emphasis drive cells with individual enablement capability are added. In some embodiments, pull-down and pull-up cells with individual enablement capability are added to provide additional configurability options. When present, the pre-emphasis, pull-down and pull-up cells are connected in parallel across the external load to provide pre-emphasis features to the output.
