MAX3793

1Gbps to 4.25Gbps Multirate Transimpedance Amplifier with Photocurrent Monitor

Maxim Integrated 

19-3467; Rev 2; 12/06

1Gbps to 4.25Gbps Multirate Transimpedance

Amplifier with Photocurrent Monitor

General 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 (CIN =

0.3pF) and 2.8mAP-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.
