R2862A

Preliminary Data Sheet October 2001 R2862A Digital 2R Receiver OC-192/STM-64 Description The R2862A 10 Gbits/s receiver is a PIN receiver with integrated transimpedance amplifier (TIA) and limiting amplifier (LA). An integrated voltage regulator provides accurate control of the TIA, thus allowing the TIA to be powered externally by a wide range of voltages. In addition, a threshold adjust provides the capability to change the eye crossing point. The threshold pin may be left open, in which case the LA self-regulates to its nominal half-way setting. Agere Systems Inc. offers several 1R and 2R highspeed receiver components for 10 Gbits/s and 12.5 Gbits/s applications. APD and PIN versions are available in a 6-pin hermetic package with coaxial output. In addition, Agere Systems also offers a PIN receiver with coplanar waveguide in a multisource agreement form-factor or a smaller, space-sensitive package.

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.
