A typical EBR-1553 implementation is composed of a digital part that can be implemented in an FPGA or ASIC, and RS-485 transceiver for the physical layer..

RS-485 transceivers are single ended as opposed to legacy-1553 transceivers which are double ended. This implies that a new decoder encoder is required in the digital portion of the EBR-1553 compared with the legacy-1553 implementation.
