Abstract
A bus interface, for allowing a plurality of devices to communicate with one another via the bus, includes a bit timing symmetrization component for symmetrizing the bit stream. For an incoming bit stream, the bit timing symmetrization component further includes an input delay filter for delaying recessive to dominant edges for a given received bit stream and sampling the delayed input signal at the sample point. In one embodiment, bit timing synchronization may still be performed with the undelayed recessive to dominant edges. For an outgoing bit stream, the bit timing symmetrization component transmits a recessive bit, that followed a previously transmitted dominant bit, before the start of the next bit time, and transmits a dominant bit, that followed a previously transmitted recessive bit, with a delay of a configurable amount of time.
