Abstract

A 1:4/1:16 demultiplexer IC with an integrated skip circuit has been successfully designed and fabricated employing SCFL standard cells based on 1 μm MESFET foundry technology. The circuit was designed to operate at up to 2.5 Gb/s with low power dissipation. The demultiplexer employs a tree type architecture based on 1:2 demux blocks using tristage flip-flops. A new skip circuit without re-timing was proposed and integrated in the demultiplexer for frame alignment. The proposed skip circuit demonstrated its effectiveness and the IC operated either as a 1:4 or a 1:16 demultiplexer at up to 2.5 Gb/s with a power dissipation of 1 W. This IC is applicable for signal processing on SONET STS-12/48 optical communication systems
