ABSTRACT:
A receiver is disclosed which operates for synchronously receiving pulses of a serial stream without synchronizing the receiver clock to the clock at a transmitting site. Circuitry is provided for generating multiple delayed pulse signals in response to each incoming pulse and for sampling and maintaining a sequence of the most recent samples of the pulse signals. Decoding logic detects state transitions within the sequence, the location therein being indicative of the phase of the pulses relative to the clock signals. The decoding logic operates other circuitry for tracking the phase of the pulses as it drifts. The phase tracking circuitry enables the selection of ones of the samples which are synchronized, or in pulse durational phase, with the receiver clock for reconstructing the incoming pulse stream.
