Abstract:
A programmable driver system that respectively provides first and second output signals at first and second output ports in a rail-to-rail mode and provides low voltage differential signaling (LVDS) output signals at said first and second output ports in an LVDS mode, the system comprising:first and second inverters respectively coupled to said first and second output ports; a low voltage differential signaling (LVDS) driver differentially coupled to said first and second output ports; and a programmable data multiplexer that respectively guides first and second input signals to said first and second inverters and biases said LVDS driver to a high output-impedance state in a rail-to-rail mode and that guides a third input signal to said LVDS driver and biases said first and second inverters to a high output-impedance state in an LVDS mode.
