Large-input-delay variation tolerant (LIDVT) receiver adopting FIFO mechanism

摘要

The present invention discloses a multiple-stage FIFO mechanism capable of receiving data signals correctly. The circuit includes a write-enable pulse sequencer for sequentially generating a plurality of write-enable signals. An N-stage FIFO sequentially stores an input data and outputs the input data. An output stage selector sequentially generates a control signal. And a multiplexer selectively outputs the input data from the N-stage FIFO.
