N-phase Polarity Data Transfer Encoding

The patent combines multiple functions (data transmission, clock signaling, control signals) into a single differential pair using multi-phase encoding. Instead of using separate pairs for each function, the invention merges them by encoding multiple bits per symbol phase, thereby reducing the number of active drivers and power consumption while maintaining high-speed data transfer capability

The patent changes the encoding parameter from traditional single-bit per symbol to multi-bit per symbol encoding with N phases. This parameter change allows more data to be transmitted per clock cycle, reducing the need for multiple differential pairs and thereby reducing power consumption and device cost

The patent merges multiple interface functions into a single differential pair by implementing multi-phase encoding that carries data, clock, and control signals simultaneously. This consolidation reduces device complexity and board real-estate requirements while maintaining high bandwidth through efficient use of the single pair

The differential pair is designed to perform multiple functions: transmitting data, carrying clock signals, and conveying control information, all within a single communication channel. This multi-functionality reduces the number of components needed and simplifies the overall interface design

The patent employs periodic phase transitions in the encoding scheme, where symbols transition through defined phase states in a regular pattern. This periodic action provides inherent clock recovery capability and synchronization, allowing the system to achieve higher speeds by eliminating jitter accumulation and reducing the impact of clock skew

The encoding scheme incorporates feedback mechanisms where the receiver detects phase transitions and uses this information to regenerate timing signals and correct for skew. This feedback loop maintains signal integrity at higher speeds by continuously compensating for timing deviations and interference
