Summary:High speed communication of digital information is accomplished using an analog transmission format. A transmitter receiving digital data in parallel multibit words converts digital words in conversion clock cycles to a single analog signal relative to a DC level. The transmitter also includes a reference pulse generator which combines a reference pulse with the analog levels generated by the converter to form an analog output for transmission to the receiver. The receiver includes a detector receiving the analog output. In response to the reference pulse, the receiver generates a recovery clock. A flash analog-to-digital converter converts the analog levels in the analog output to multi-bit digital outputs. The parallel multi-bit words are regenerated in recovery clock cycles from sampling the multi-bit digital output once per cycle. Thus, by using a digital to analog to digital systems, effective bit rates are achieved that are higher than the switching speeds of the transmitter and receiver.
