AGERE 2606B Datasheet
2606B Return-Path Photodiode Receiver Module
Description
The 2606B CA TV return-path photodiode module is a
critical component for the delivery of high-performance interactive services for today's two-way fiberoptic networks. These modules utilize PIN InGaAs
photodiodes in robust 14-pin DIL packages that
exhibit excellent sensitivity, low noise, and exceptional linearity in return-path optical links. The module incorporates a patented impedance-matching
circuit, which optimizes very low noise gain in optical
broadband receivers.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
