Method and circuitry for transmitting data

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.

1. A data transfer system, comprising:
a first circuit having:
input data channels configured to receive data for transmission;a serializer configured to determine whether each of the input data channels is active or inactive, and the serializer configured to serialize the data in the active input data channel and ignore the inactive input data channel; andan output amplifier coupled with the serializer, the output amplifier configured to amplify the serialized data for transmission; and a second circuit coupled with the first circuit, the second circuit having a deserializer configured to deserialize the transmitted data.
