ABSTRACT:
A method and system for a configurable Vcc reference and Vss reference differential current mode transmitter is described. The system includes a Vss reference differential current mode driver, a Vcc reference differential current mode driver coupled to the Vss reference current mode driver, and a controller circuit coupled to the Vss reference differential current mode driver and the Vcc reference differential current mode driver to select between the Vss reference differential current mode driver and the Vcc reference differential current mode driver based on a type of transmission interface.
