M02016

1

CMOS Transimpedance Amplifier with AGC

for Fiber Optic Networks up to 1.25 Gbps

Rev V4

Applications

•GPON

•GEPON

•

Gigabit Ethernet

•

Fiber Channel

The M02016 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 35 dB. The

high transimpedance gain of 24 k

Ω ensures good sensitivity.

For optimum system performance, the M02016 die should be mounted with a silicon or InGaAs PIN photo detector

inside a lensed TO-Can or other optical sub-assembly.

The M02016 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.
