CMOS Pre-amplifier with AGC for Long-reach

155 Mbps Fiber-optics Based Transmitter

Rev V4

3.0 Functional Description

3.1

Overview

The M02006 is a low-noise, transimpedance amplifier with AGC, manufactured in sub-micron CMOS. Its wide

dynamic range, differential output and high PIN bias make it well suited for telecommunications, especially OC-3/

STM-1. However, the M02006 is intended to meet the needs of both Telecom and Datacom users.

The M02006 is available only in die form. For optimum system performance, die should be mounted in close

proximity with the photodetector.

The M02006 is designed to be used with the MC2045 postamplifier IC. When combined with a photodiode, the chip

set forms a high performance, low cost 5 V receiver.
