摘要: Circuitry and methods are provided for an LVDS-like transmitter that may be able to DC couple a receiver having CML termination scheme. Replacing the common mode voltage source of LVDS with resistive pulldown ground allow interface in coupled fashion receiver. Further, programmable. This support wider customer base by allowing it range levels, such as levels.
