Infineon Technologies AG has presented at the electronica 2002 a mux/demux chipset manufactured using a 0.13?m CMOS process and achieves a transmission rate of up to 40Gbps. The company earlier achieved an RF CMOS IC data rate of 25Gbps.

The achievement of the data rate represents a performance breakthrough for CMOS HF circuits, as the 40Gbps rate was previously only possible using SiGe, GaAs, or InP process. CMOS technology provides a high integration density and allows complex logic to be integrated with currently available high-speed circuits.

"Infineon is setting new standards with these RF-CMOS circuits and is reasserting its leading technical position in the semiconductor market," stated Dr. Soenke Mehrgardt, CTO and board member at Infineon. "This and other successes are the result of the hard work and investments that Infineon has made within the scope of its global research and development activities."

The mux/demux chipset was implemented using a current mode logic and a differential 50-ohm I/O. The 40Gbps transmission rate originates from pre-latch configuration, transistor size, operating current per stage, gain peaking due to inductive loads, and a new type of output signal transmission optimization.

The 2:1 data mux achieved a maximum transmission rate of 43Gbps and used a 1.5V power supply, while consuming 66mA. The 2:1 data demux achieved 40Gbps and was powered from a 1.5V source.
