    Abstract: A source driving circuit includes a gamma voltage generator, a common voltage generator and a driver. The gamma voltage generator receives gamma data from a timing controller through reduced swing differential signaling (RSDS) transmission interface to generate corresponding gamma voltages. The common voltage generator receives common voltage data from the timing controller to generate a corresponding common voltage. The driver receives image data from the timing controller through the RSDS transmission interface, the gamma voltages from the gamma voltage generator and the common voltage from the common voltage generator for modifying the image data using the gamma voltages and the common voltage and transmitting the modified image data to a panel of the liquid crystal display.

    Abstract: A method for adjusting a serial data signal having multiple sets of bits includes the following steps. First, one set of bits in the serial data signal is over-sampled to generate a first set of over-sampled bits. Next, every adjacent two bits of the first set of over-sampled bits are compared to generate one set of edge bits. Then, a delay operation is determined according to the set of edge bits. Afterwards, a displacement operation is executed on next sets of bits in the serial data signal according to the delay operation.

    Abstract: It is difficult to implement a conventional phase lock loop circuit in a sink device within an HDMI system because the low frequency input causes the conventional phase lock loop circuit to absorb unnecessary noise during a long waiting period. Therefore, the present invention provides a low jitter clock regenerator comprises: an input clock; a divider to divide said input clock into a slower clock; a phase lock loop circuit to regenerate said slower clock to a reference clock; and a parameter transformer to tune said divider and said phase lock loop circuit to increase the adjustment speed of said phase lock loop circuit. The present invention also provides a method to reorganize parameters in order to create new parameters which are better suitable for a clock recovery circuit in a sink device within an HDMI system.

    Abstract: A data transmission system includes a transmitter and a receiver. The transmitter mixes an original clock signal and an original data signal to generate and output a hybrid differential signal, the hybrid differential signal having multiple clock pulses and multiple data pulses. At lease one data pulse occurs between two clock pulses, and the period between two clock pulses corresponds to the frequency of the original clock signal. The clock pulses and the data pulses have different differential swings. The receiver receives the hybrid differential signal via a bus and generates a recovered clock signal and a recovered data signal based on the hybrid differential signal. The hybrid differential signal, the original clock signal and the original data signal are reduced swing differential signals.
