1.25Gbps/2.5Gbps, +3V to +5.5V, Low-Noise

Transimpedance Preamplifiers for LANs

General Description

Features

ꢀ 200nA Input-Referred Noise (MAX3266)

The MAX3266 is a transimpedance preamplifier for

1.25Gbps local area network (LAN) fiber optic

receivers. The circuit features 200nA input-referred

noise, 920MHz bandwidth, and 1mA input overload.

ꢀ 920MHz Bandwidth (MAX3266)

1900MHz Bandwidth (MAX3267)

ꢀ 1mA Input Overload

The MAX3267 provides a pin-for-pin compatible solu-

tion for communications up to 2.5Gbps. It features

500nA input-referred noise, 1.9GHz bandwidth, and

1mA input overload.

ꢀ +3.0V to +5.5V Single-Supply Voltage

Ordering Information

Both devices operate from a +3.0V to +5.5V single sup-

ply and require no compensation capacitor. They also

include a space-saving filter connection that provides

positive bias for the photodiode through a 1.5kΩ resistor

to V . These features allow easy assembly into a TO-46

or TO-56 header with a photodiode.

Dice*

The 1.25Gbps MAX3266 has a typical optical dynamic

range of -24dBm to 0dBm in a shortwave (850nm)

configuration or -27dBm to -3dBm in a longwave

(1300nm) configuration. The 2.5Gbps MAX3267 has a

typical optical dynamic range of -21dBm to 0dBm in a

shortwave configuration or -24dBm to -3dBm in a long-

wave configuration.
