10 Gbps Post-Amplifier

CX60083

The CX60083 is an ideal device for high-speed fiber-optic module

manufacturers. The 10 Gbps limiting amplifier is one of the

industry’s first devices to provide integrated loss-of-signal and

peak-detect circuits in a high-speed, compact, 32-pin plastic TQFP.

Providing the correct mix of gain and dynamic range, the CX60083

lets designers build fiber-optic modules with stable characteristics,

even at data rates of 10.7 Gbps.
