Abstract

A high-speed burst digital time multiplexed data system has N parallel input data paths that are multiplexed onto a serial data path for transmission from a transmitter to a receiver. Serial transmission takes place in a short burst upon command at the transmitter. Data from the serial data path is demultiplexed back into N parallel data paths at the receiver. The entire process is accomplished asynchronously without the aid of a clock or framing signal. In the preferred embodiment, a train of N sampling pulses is generated by two tapped delay lines, one at the transmitter and one at the receiver. The length of each sequential sampling pulse is determined by the tap spacing of the delay line, and the duration of the entire burst process is equal to the total delay of the delay line. A new burst may be initiated at any time after the completion of the previous burst. Thus bursts may follow each other immediately or be arbitrarily spaced to occur whenever data transmission is required.
