摘要： A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module.

摘要： Isolation circuits for digital communications and methods to provide isolation for digital communications are disclosed. An example isolation circuit includes an isolation barrier, a burst encoder in a first circuit, and an edge pattern detector in a second circuit. The example isolation barrier electrically isolates the first circuit from the second circuit. The example burst encoder generates a first pattern in response to receiving a rising edge on an input signal and generates a second pattern in response to receiving a falling edge on the input signal. The example edge pattern detector detects the first pattern or the second pattern received from the burst encoder via the isolation barrier, sets an output signal at a first signal level in response to detecting the first pattern, and sets the output signal at a second signal level in response to detecting the second pattern.

摘要： Data transfer devices and methods for transferring data between first and second circuits are disclosed. A data transfer device includes a first circuit having a plurality of data channels, wherein at least one of the data channels is an active data channel. A serializer has a plurality of inputs and an output, wherein the inputs are coupled to the plurality of data channels. The serializer is for coupling only one active channel at a time to the output. An isolation barrier is coupled to the output of the serializer, the isolation attenuates transients and passes the fundamental frequency. A second circuit includes a deserializer having an input and at least one output, the input is coupled to the isolation barrier, the at least one output is at least one active data channel.
