Abstract

An alternative architecture for instantaneous data recovery for burst-mode communication is introduced. The architecture can perform 1:n demultiplexing without additional clock recovery phase-locked loop or sampling blocks. A finite-state machine (FSM) is formed with combinational logic and analog LC transmission line delay cells in a feedback loop. The FSM responds to input data transitions instantaneously and sets the outputs. The system reduces unit interval jitter by a factor of n. The new architecture is demonstrated via a SiGe 1:2 clockless demultiplexer circuit that operates at 7.5 Gb/s.
