CMOS Transimpedance Amplifier with AGC

Rev V8
3.0 Functional Description
3.1
Overview
The M02013 is a transimpedance amplifier (TIA) with AGC manufactured in a sub-micron, CMOS process. The
AGC allows more than 25 dBm of dynamic range, providing a low-cost solution for longer-reach 3.2 Gbps ATM/
SONET systems.
For optimum system performance, the M02013 die should be mounted with a silicon or InGaAs PIN photodetector
inside a lensed TO-Can or other optical sub-assembly.
he M02013 can either bias the PIN diode from the internal regulator or use an externally biased PIN diode.
A replica of the average photodiode current is available at the MON pad for photo-alignment and 'Loss of Signal'
(LOS) monitoring.
