摘要
A 12.5 Gbps 1:16 demultiplexer (DEMUX) integrated circuit is presented for multi-channel high-speed data transmission. A novel high-speed synchronizing technique is proposed and integrated in this DEMUX chip. Compared with conventional synchronizing techniques, the proposed method largely simplifies the system config- uration. The experimental result demonstrates that the proposed circuit is effective in two-channel synchronization under a clock frequency of 12.5 GHz. The circuit is realized using 1 μm GaAs heterojunction bipolar transistor technology with die area of 2.3 ×2.3 mm^2.
