Abstract
A secure communication circuit for use with a data communication interconnect adapter and method of operation thereof. The secure communication circuit includes a first data buffer coupled to a data input terminal, an encoder/decoder coupled to the first data buffer, a second data buffer coupled to the encoder/decoder and a switching device coupled to a data output terminal. The switching device is couplable to either the first or second data buffers. A controller, coupled to the (switching device, selectively connects the switching device to the first or second data buffers. In a related embodiment, the secure communication circuit further includes a first serializer/deserializer (SERDES) coupled to the data input and a second SERDES coupled to the switching device.
