Abstract
A signal conversion system for interfacing selected components of a communication system and methods for manufacturing and using same. The signal conversion system converts selected logic signals from one system component into a pair of differential logic signals and provides the pair of differential logic signals to a second system component, resolving any logical and/or temporal artifacts. While one or more of the selected logic signals change signal state, the signal conversion system maintains the pair of differential logic signals in a first valid combined signal state until the signal state of the selected logic signals corresponds to a second valid combined signal state for the pair of differential logic signals. The signal verification system then updates the pair of differential logic signals to have the second valid combined signal state. The system components thereby can communicate, exchanging differential communication signals while maintaining duty cycle and avoiding signaling glitches.
