Abstract
A dual-mode LVDS/CML transmitter allows a single circuit to operate as either an LVDS transmitter or a CML transmitter. The transmitter mode can be switched by activating or deactivating appropriate circuit elements, and changing the voltage or current produced by appropriate sources or sinks. This flexibility allows a single transmitter to operate well in both AC and DC coupling conditions, and facilitates interoperation with a greater variety of receivers.
