Description

The MAX3793 transimpedance amplifier provides a compact low-power solution for applications from 1Gbps up to 4.25Gbps.

The MAX3793 features 195nA input-referred noise, 3.5kΩ transimpedance gain, 2.9GHz bandwidth (C_IN = 0.3pF) and 2.8mA_P-P input overload. Operating from a +3.3V supply, the MAX3793 consumes only 106mW. An integrated filter resistor provides positive bias for the photodiode. These features, combined with a small die size, allow easy assembly into a TO-46 header with a photodiode. The MAX3793 also includes an average photocurrent monitor.

The MAX3793 has a typical optical sensitivity of -20dBm (0.55A/W) at 4.25Gbps. Typical optical overload is at 4dBm. The MAX3793 and the MAX3748A limiting amplifiers provide a complete solution for multirate receiver applications.
