A transmitter module, a receiver module and a communication system for exchanging Ethernet Medium Access Control (MAC) frames on a single Multipoint Low Voltage Differential Signaling (M-LVDS) line. The transmitter module includes: a first transmitter media-independent interface (MII) including parallel data lines for receiving bits of an Ethernet MAC frame to be transmitted on the single M-LVDS line: an 8b/10b encoding unit adapted to encode 8-bit words to produce 10-bit words, wherein the 8-bit words include bits of the Ethernet MAC frame received on the parallel data lines of the first transmitter MII; a serializing unit adapted to serialize the 10-bits words; and an M-LVDS transmitter unit for transmitting the serialized 10-bit words on the single M-LVDS line.

Transmitter and receiver module, communication system for exchanging ethernet frames on a single M-LVDS line

An industrial system for controlling backplane communication including a cluster manager linked to Input/Output modules via a multipoint low voltage differential signaling, MLVDS, bus through passive base plates. The MLVDS bus contains a transmission line and a reception line for the cluster manager. The transmission line of the MLVDS bus is shared by the Input/Output modules for receiving data transmitted by the cluster manager. The reception line of the MLVDS bus is shared by the Input/Output modules for transmitting data to the cluster manager. The Input/Output modules are synchronized in time with the cluster manager and configured to send data on the reception line of the MLVDS bus at respective scheduled time windows.
