Abstract :
A 10 Gb/s 1:8 frame detecting demultiplexer requires 50% less accuracy of frame detection timing control. This 10 Gb/s demultiplexer with frame detection is fabricated using a SiGe Bipolar process. The relaxation of the accuracy requirement is achieved by a data shift selection architecture. This IC is constructed by a combination of a data shift selection circuit and a parallel shift register circuit. In this architecture, the most accurate control is required in a counter operating at 5 GHz. The core circuit of the IC dissipates only 1.8 W with -4.5 V supply voltage.
