Abstract
An apparatus for self-calibration in isolated communication is included. A plurality of integrated circuits perform isolated communication with respect to each other. A microcomputer is configured to output a self-calibration instruction to the plurality of integrated circuits when a predetermined condition is met or in response to at least one of a periodic instruction or an aperiodic instruction. A plurality of processors are respectively provided in a corresponding one of the plurality of integrated circuits. Each of the processors being configured to perform a self-calibration operation to transmission parts and receiving parts in the corresponding integrated circuit.
Claims18
An apparatus, comprising:
- a plurality of integrated circuits configured to perform isolated communication with respect to each other;
- a microcomputer configured to output a self-calibration instruction to the plurality of integrated circuits when a predetermined condition is met or in response to one of a periodic instruction or aperiodic instruction;
- and
- a plurality of processors each provided in a corresponding one of the plurality of integrated circuits, the plurality of processors being configured to execute instructions to perform a self-calibration operation to transmission parts and receiving parts in the corresponding integrated circuit,
- wherein, when the self-calibration instruction is input, the instructions further comprise instructions to change a level of a receiving part input signal by controlling voltage change times of a rising edge of a transmission part output signal and a falling edge of the transmission part output signal.
An apparatus, comprising:
- a plurality of integrated circuits configured to perform isolated communication with respect to each other;
- a microcomputer configured to output a self-calibration instruction to the plurality of integrated circuits when a predetermined condition is met or in response to one of a periodic instruction or aperiodic instruction;
