摘要： The present technology relates to a signal processing device, a signal processing method, and an electronic device that reduce the influence of crosstalk. In one example, a signal processing device includes a plurality of comparators; a delay unit adapted to delay output of each of the plurality of comparators; and a subtractor adapted to subtract, from a supplied signal, a signal from the delay unit. The signal processing device processes signals transmitted in N phases and includes (N-1) or more comparators. Each of the plurality of comparators has a different threshold value set and compares a received signal with the threshold value, and in a case where the signal transitions between a plurality of voltage levels, the threshold value is set to a value within adjacent voltage levels. In a second example, a reception device that receives a signal transmitted in multiple phases and via multiple lines.

摘要： Devices exchange control signals with each other to ensure proper operation of an overall system. For instance, in a communication system, a baseband processor and a transceiver communicate with each other to exchange information for controlling the respective signal processing parts of the baseband processor and the transceiver. While Serial Peripheral Interfaces (SPIs) can be used, SPI can be extremely slow, and does not provide a protocol for allowing a complex set of control signals to be exchanged between the baseband processor and transceiver. The present disclosure describes a fast control interface which can support various modes of operation in allowing two devices to communicate with each other quickly and effectively.

摘要： A power line communication apparatus includes a drive block including an actuator control circuit and a drive circuit and a communication block. The actuator control circuit generates a control pulse for controlling an actuator, and controls a transition timing of the control pulse during an operation period set within a communication cycle by a communication clock. The drive circuit controls a driving current of the actuator supplied from a DC power source through a power line based on the control pulse in which the transition timing is controlled. The communication block generates the communication clock, and modulates a current flowing through the power line in response to data to be transmitted during a signal transmission period different from the operation period, set within the communication cycle.

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.
