Abstract
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.
