METHOD FOR COMMUNICATION BETWEEN A FIRST PASSIVE SUBSCRIBER AND A SECOND PASSIVE SUBSCRIBER OF A BUS SYSTEM

A method is provided for communicating between passive subscribers of a bus system. A first passive subscriber encodes an original static pattern in a first transmit SERDES element and encodes original user data in a time-synchronized manner with the original static pattern in a second transmit SERDES element. The second passive subscriber receives the encoded static pattern and user data, and generates a sampling clock having a first phase offset and a clock synchronous with a transmit-receive clock having a second phase offset, from the encoded static pattern. The second passive subscriber decodes the encoded static pattern using a first receive SERDES element and the encoded user data, using a second receive SERDES element to obtain a receive data word. The first receive SERDES element and the second receive SERDES element are operated based on the sampling clock, and the receive data word is output synchronously with the synchronous clock.
