摘要： A cable including circuitry for asserting information to a user or external device and a system including such a cable. The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device). Other aspects of the invention are methods for accessing cable data stored in a cable and optionally using the data (e.g., to implement equalization). The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.

摘要： An output amplifier is provided for use in a bidirectional communications interface, for example, connecting a transmitter and a receiver to a transmission line. The output amplifier includes a differential amplifier pair connected to output circuitry. The differential amplifier pair receives differential data signal pairs from each of a transmission line and a transmitter. The output circuitry receives signals from the differential amplifier pair and, in response, forms single-ended output logic signals. The output amplifier suppresses electronic input noise throughput using an asymmetric transfer characteristic that offsets output signal logic levels with respect to input noise signal levels. The asymmetric transfer characteristic is produced by skewing a transfer characteristic of the differential amplifier pair using an asymmetrical transistor configuration at an output side of the differential amplifier pair. The output logic signals represent data received on the transmission line, and are provided to the receiver.

摘要： The present invention relates to a serial interface transmission system with more than one data line, in which the transmitted data has in-band and out-of-band characters. More particularly, the present invention relates to methods and systems for sending side channel data over a high-speed digital communications link, e.g., a video link. One embodiment of the invention provides a high-speed digital transmitter capable of sending side channel data. The transmitter includes a channel zero encoder, a multiplexer, data enable out (DEout) control logic, and a channel one encoder. The channel one encoder receives input from the channel one multiplexer and the channel one DEout control logic. Another embodiment of the invention provides a high-speed digital receiver capable of receiving side channel data. The receiver includes a channel zero decoder, a channel one decoder, DEI signal and FIFO control signal recovery logic, and a channel one de-multiplexer. The DEI signal and FIFO control signal recovery logic receives input from the channel one decoder. Similarly, the channel one demultiplexer receives input from the channel one decoder.

摘要： A system and method for measuring and utilizing a pseudo pixel error rate in digital data transmission is disclosed. As an alternative to measuring actual pixel error rate measurement, the present invention uses a pseudo pixel error rate detection scheme where the errors occurred in the special character patterns used in data encoding are measured. A particular embodiment uses a de-glitch filter for filtering the glitches from an unfiltered data enable (DE), a delay for delaying the unfiltered DE to match the delay of the de-glitch filter, and a comparator for comparing the unfiltered DE and the filtered DE to determine the occurrence of an error. It further includes a counter to count the errors occurred.

摘要： The system preferably includes a unique transmitter that sends both clock and data signals over the same transmission line. The receiver uses the same transmission line to send data signals back to the transmitter. The transmitter comprises a clock generator, a decoder and a line interface. The clock generator produces a clock signal that includes a variable position falling edge. The falling edge position is decoded by the receiver to extract data from the clock signal. The receiver comprises a clock re-generator, a data decoder and a return channel encoder. The clock re-generator monitors the transmission line, receives signals, filters them and generates a clock signal at the receiver from the signal on the transmission line. The return channel encoder generates signals and asserts them on the transmission line. The signal is asserted or superimposed over the clock & data signal provided by the transmitter.
