Cognet Microsystems, a provider of high-speed fiber optic solutions to the data networking and telecommunications industry, announced the industry's first 10Gbps Limiting Amplifier in standard Complementary Metal Oxide Semiconductor (CMOS) process technology.

Cognet Microsystems, a provider of high-speed fiber optic solutions to the data networking and telecommunications industry, announced the industry's first 10Gbps Limiting Amplifier in standard Complementary Metal Oxide Semiconductor (CMOS) process technology. The new technology will enable manufacturers to build low-cost fiber optic modules for OC192 SONET and 10 Gigabit Ethernet applications.

Cognet uses the standard CMOS process to manufacture this product, compared to its competitors who depend on exotic processes such as GaAs or SiGe. The Limiting Amplifier utilizes Cognet's proprietary Broadband Cascade Amplifier (BCA) a novel circuit architecture that allows CMOS to achieve broadband performance previously attained only through SiGe or GaAs processes.

At 300mW, the CN10KRL consumes approximately half the power of competitor's products. The chip operates from a 1.8-volt supply voltage, offers 5 mV sensitivity with better than 40 dB gain, and a low jitter performance of 2ps (rms).

The 10Gbps Limiting Amplifier is currently available in die form in sample quantities.
