Abstract

A substantially simultaneous digital data regeneration and deserialization technique for communication systems and information and data processing systems is disclosed. A digital phase lock logic circuit (DPLL) receives the serial stream of clock and data bits at its input and outputs a plurality of clock signals with different phase. A plurality of latches are coupled to receive a respective one of the clock output signals from the DPLL. Each latch receives the serial stream of clock and data bits through a second input such that the latches are sequentially set by substantially simultaneously received clock and data information at the two inputs and the serial data bits within the stream appear as parallel data bits at the latch outputs. Enhanced versions of this circuit are also described, along with an alternate embodiment which uses an analog phase locked loop circuit.
