    摘要： In an example, a system includes circuitry on a first side of an isolation barrier and circuitry on a second side of the isolation barrier, where the isolation barrier is operable to electrically isolate the first side from the second side. The system also includes a trimmed oscillator, a first transmitter, and a first receiver on the first side, the trimmed oscillator coupled to the first transmitter. The system includes a tunable oscillator, a second transmitter, and a second receiver on the second side, the tunable oscillator coupled to the second receiver and the second transmitter. In the system, the first side is configured to transmit a training sequence to the second side, and the second side is configured to tune the tunable oscillator based on the training sequence.

    摘要： A transmission/reception method and device for isolated communication is proposed. The transmission/reception method includes performing transmission, wherein bit streams are extracted from data and two or more predetermined number of bits are modulated into one DC balanced symbol so as to generate a signal in which a plurality of symbols are listed, thereby transmitting the signal through an isolated communication circuit, and performing reception, wherein the signal is received through the isolated communication circuit and the plurality of symbols included in the signal are demodulated into the two or more predetermined number of bits so as to generate the bit streams and organize the bit streams into the data. The transmission/reception method and device may reduce power consumption at the same communication speed because a plurality of bits is represented by the one DC balanced symbol.

    摘要： The present invention provides a common-mode transient suppression protection circuit for a digital isolator, including a modulation circuit, a demodulation circuit and an isolation capacitor connected between the modulation circuit and the demodulation circuit. The modulation circuit includes a modulation circuit front-end and a drive circuit, which are connected in sequence, and a clamping module is arranged in the drive circuit. The protection circuit further includes a linear voltage regulator structure connected with the drive circuit, and a power supply clamp is arranged in the linear voltage regulator structure. By providing the linear voltage regulator structure having the power supply clamp and the drive circuit having the clamping module in the protection circuit, low-voltage devices in the drive circuit can be protected from being damaged by high-voltage signals generated by common-mode transient interference.

    摘要： Several circuits and methods for transferring an input data signal in a digital isolator are disclosed. In an embodiment, the digital isolator includes an isolation element, input circuit, and output circuit. The isolation element includes at least one input node and at least one output node, the input circuit is electronically coupled to the input node and generates modulated differential data signals based on modulating the input data signal on a carrier signal. The input circuit operates using a first supply voltage with respect to a first ground. The output circuit is electronically coupled to the output node to receive the modulated differential data signals, operates using a second supply voltage with respect to a second ground and includes a frequency-shift keying demodulator configured to generate a demodulated data signal in response to detection of presence of the carrier signal. The output circuit further generates an output data signal.

    摘要： An isolation coupler comprises a frequency splitter (36) for splitting an input signal (1) into a low frequency partial signal (2) and a high frequency partial signal (4) and a first isolating transformer (33) for transforming a signal derived from the high frequency partial signal (4) in a transformed high frequency partial signal (5). Moreover it may include a modulator (21) for modulating the low frequency partial signal (2) with a modulation signal (6) resulting in a modulated low frequency partial signal (7) and a second isolating transformer (34) for transforming a signal derived from the modulated low frequency partial signal (7) in a transformed low frequency partial signal (8).
