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 high-
speed 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. For more information about the complete
line of high-speed receiver products, please visit the
Agere Systems' website at www.agere.com/opto.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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.
* Based on human-body model of R = 1500
and C =100 pF. In general, precautions should be taken to avoid damage to the device.
