摘要： In a data transmission system, one or more signal supply voltages for generating the signaling voltage of a signal to be transmitted are generated in a first circuit and forwarded from the first circuit to a second circuit. The second circuit may use the forwarded signal supply voltages to generate another signal to be transmitted back from the second circuit to the first circuit, thereby obviating the need to generate signal supply voltages separately in the second circuit. The first circuit may also adjust the signal supply voltages based on the signal transmitted back from the second circuit to the first circuit. The data transmission system may employ a single-ended signaling system in which the signaling voltage is referenced to a reference voltage that is a power supply voltage such as ground, shared by the first circuit and the second circuit.

摘要： Embodiments of the present invention may provide a system with a first and second circuit system separated by an electrical isolation barrier but provided in communication by at least one isolator device that bridges the isolation barrier. The first circuit system may include a communication system to transmit data across a common isolator device as a series of pulses, and the second circuit system may receive the series of pulses corresponding to the data. The second circuit system may include a detector coupled to the common isolator device to detect the received pulses, a oneshot to frame the received pulse(s), and a controller to reconstruct the data based on accumulated framed pulse(s). Therefore, noise induced spurious pulses outside the oneshot intervals may be ignored by the second circuit system providing improved noise immunity.

摘要： A first integrated circuit (IC) has an adjustable delay circuit and a first interface circuit. A first clock signal is provided to the adjustable delay circuit to produce a delayed clock signal provided to the first interface circuit. A second IC has a supply voltage sense circuit and a second interface circuit that transfers data with the first IC. The supply voltage sense circuit provides a noise signal to the first IC that is indicative of noise in a supply voltage of the second IC. The adjustable delay circuit adjusts a delay of the delayed clock signal based on the noise signal. In other embodiments, edge-colored clock signals reduce the effects of high frequency jitter in the transmission of data between integrated circuits (ICs) by making the high frequency jitter common between the ICs. In other embodiments, a supply voltage is used to generate clocks signals on multiple ICs.

摘要： A system for transmitting data from a timing controller (TCON) to several source driver integrated circuits (SICs) in a display. The system is suitable for use either with a high data rate or a low data rate to each of the SICs. The TCON provides a serial data stream to a SIC, which either uses all of the received data, if it requires high rate data, or relays a portion, e.g., half, of the data to another SIC, which then does not require a separate direct connection to the TCON.

摘要： The present disclosure provides apparatus and methods for dynamic analog tuning for power reduction. As disclosed herein, the analog controls on a high-speed serial communication channel are dynamically adjusted in a manner so as to either reduce the total system power or move power dissipation between the transmitter and receiver devices, with little or no negative effect to the bit error rate. One embodiment relates to a method for tuning a communication link. The method includes occasionally determining whether the bit error rate for the communication link is acceptably low. Control parameters for analog circuitry of the communication link are adjusted to decrease power used if the bit error rate is acceptably low and are adjusted to increase power used if the bit error rate is not acceptably low. Other embodiments, aspects and features are also disclosed.

摘要： A management data area including a plurality of pulsed signals is provided in a series of pulsed signals outputted from the main station to the common data signal line, the area being different from a control/monitoring data area including data of a control data signal and data of a monitoring data signal. The substation sets random number data generated by its own station as an original number, generates pieces of comparison/collation data having a plurality of bits based on the original number, and superimposes a signal including the pieces of comparison/collation data on the management data area. The main station determines existence of address overlap of the substations based on a result of comparing the pieces of comparison/collation data complying with a predetermined rule.
