    Abstract: PROBLEM TO BE SOLVED: To differentially transmit high-speed data using a forward channel through a serial link, and transmit comparatively low-speed data that are differentially modulated to forward channel signals using a backward channel through a link.
    SOLUTION: Differential modulation is used for both of forward and backward channels, so that signals have a substantially constant common mode voltage and generate low EMI. The spectrum content of signals related to high-speed data may not be substantially overlapped to the spectrum content of signals related to low-speed data. Thereby, high-speed and low-speed data are reproduced at minimum interference. The differential signaling transmission itself transfers data through an inexpensive medium, such as twisted wire pair or parallel PCB trace. The data transmission technologies are applied to various communication network topologies, and point-to-point, daisy-chain and one-to-many communications.
