Abstract: A LVDS and TMDS dualfunction transmitter for both LVDS and TMDS output channels is disclosed, including an encoder and a serializer. The encoder encodes twenty eight bits of LVDS signals to thirty bits of TMDS signals. The serializer includes four serializer channels for converting the LVDS signals to a serial signal when a LVDS mode is enabled, or converting the TMDS signals to the serial signal when a TMDS mode is enabled. Wherein a first serializer channel is coupled to seven bits of the LVDS signals and outputting a first pair of differential signals. Second, third and fourth serializer channel are coupled to seven bits of the LVDS signals and ten bits of TMDS signals, and outputting a second, third and fourth pair of differential signals, respectively.

Abstract: A combined output driver for TMDS signals and LVDS signals. First and second output drivers output first and second differential signals to a first external input unit and a second external input unit, respectively, through a pair of signal lines according to first and second input signals. In the second output driver, a driver buffer is coupled to a first voltage and a first node respectively to generate two control signals according to the second input signals. An output unit generates the second differential signal according to the two control signals. A power supply provides a second voltage higher than the first voltage to power the driver buffer and the output unit when the first output driver outputs the first differential signal to the first external input unit.

Abstract: A combined transmission unit for TMDS signals and LVDS signals. A first (LVDS) transmission unit includes a set of first input terminals to receive first data, and a second (TMDS) transmission unit includes a set of second input terminals to receive second data. A phase locked loop (PLL) generates a first set of output clock signals to the first transmission unit in a first mode and a second set of output clock signals to the second transmission unit in a second mode according to a mode selection signal. The first and second transmission units are able to transmit the first data to the first and second external input units in the first and second modes respectively, according to the mode selection signal and the first and second sets of output clock signals.

Abstract: The present invention relates a printed circuit board having jumper lines, and a method for making the printed circuit board. An isolation layer made of a dielectric material is coated on the line layer of the printed circuit board, and multiple pads are formed in the isolation layer, thereby exposing part of the line layer without covered by the isolation layer. A high conductive material is coated on the isolation layer to connect the multiple pads, thereby forming a planar jumper layer that is connected to the line layer through the circular pads. Thus, the planar jumper layer may be made simultaneously during fabrication of the printed circuit board, without having to perform the wire-bonding work.
