155Mbps Low-Noise Transimpedance Amplifier

Maxim Integrated

155Mbps Low-Noise Transimpedance

Amplifier

General Description

The MAX3657 is a transimpedance preamplifier for

receivers operating up to 155Mbps. The low noise, high

gain, and low-power dissipation make it ideal for Class-B

and Class-C passive optical networks (PONs).

The circuit features 14nA input-referred noise, 130MHz

bandwidth, and 2mA input overload. Low jitter is

achieved without external compensation capacitors.

Operating from a +3.3V supply, the MAX3657 con-

sumes only 76mW power. An integrated filter resistor

provides positive bias for the photodiode. These fea-

tures, combined with a small die size, allow easy

assembly into a TO-46 header with a photodiode. The

MAX3657 includes an average photocurrent monitor.

The MAX3657 has a typical optical sensitivity of -38dBm

(0.9A/W), which exceeds the Class-C PON require-

ments. Typical overload is 0dBm. The MAX3657 is avail-

able in die form with both output polarities (MAX3657E/D

and MAX3657BE/D.) The MAX3657 is also available in a

12-pin, 3mm x 3mm thin QFN package.
