Abstract: An application module, that is part of an electronic assembly including a controller module, is coupled to a backplane bus structure. The backplane comprises a differential bus(s) having a TX and RX data signal, a differential clock signal, and a single ended collision detection line. The application module comprises differential bus transceivers that are controlled by differential bus control logic on the application module. The control logic compares data bits received over a collision detection line with the data bits the application module originally transmitted. If the data is not the same, a collision has occurred and the control logic places the bus transceivers into a high impedance state. A data packet controller on the application module can only detect certain types of collisions that occur in the single ended environment. The control logic enables the data packet controller to recognize a collision that it normally would not.
