摘要： A multiplexer and methods thereof. In an example, the multiplexer may receive a first periodic signal with a first active duration and a second periodic signal with a second active duration, the first and second active durations not overlapping. The multiplexer may transition statuses of first and second transmission gates based on the first and second periodic signals, respectively, such that each of the first and second transmission gates are set to the same status during at least one time period (e.g., between the first and second active durations where both the first and second periodic signals are inactive). In a further example, the example multiplexer may include first and second transmission gates receiving first and second input signals which may be controlled by the first and second control signals.

摘要： A pre-emphasis circuit capable of controlling the slew rate of a signal output from a buffer that transfers the output signal to an output driver to increase the range of a controllable voltage step includes a first buffer, a second buffer, and an output driver. The first buffer buffers first and second main input signals having phases opposite to each other, outputs first and second main output signals, and controls slew rates of the first and second main output signals using at least one main control signal. The second buffer buffers first and second sub-input signals having phases opposite to each other, outputs first and sub-output signals, and controls slew rates of the first and second sub-output signals using at least one sub-control signal. The output driver generates first and second output signals having opposite phases using at least two control signals and the output signals of the first and second buffers.

摘要： A termination circuit for a HDMI transmitter includes a bias unit and a termination resistor unit connected in parallel between a positive transmission pin and a negative transmission pin. The bias unit generates a bias voltage by selecting the higher voltage among a first voltage received through the positive transmission pin and a second voltage received through the negative transmission pin. The termination resistor unit is formed on a well region biased by the bias voltage, and conditionally provides a termination resistance between the positive transmission pin and the negative transmission pin in response to a termination resistor control signal. The termination circuit conditionally provides a termination resistance without a leakage current. The termination resistance may be varied by using an n-bit control code.

摘要： A serializer serializes N data (N>2) in N stages into a serial data stream. Each stage includes a logic section and a first inverter. The logic section receives i-th data (where i is less than or equal to N) of the N parallel data to output the i-th data or inverted i-th data in response to an active status or an inactive status of an j-th clock signal (where j is less than or equal to N) of the N clock signals. The first inverter receives the i-th data or the inverted i-th data from the logic section and inverts the i-th data or the inverted i-th data to output a first output signal. The output signal of the serializer may have reduced jitter even when the serializer operates in a high speed and a low power condition.

摘要： In the method of controlling a slew rate, a transmission line driver may set a logic level of at least one control signal. The setting of the logic level of the at least one control signal determines a resistance on at least one path within the transmission line driver. The resistance may be adjusted so as to vary a slope of at least one driving voltage and achieve a desired slew rate.
