iT3010
10 GHz Medium-Gain Differential Amplifier
Description
www.DataSheet4U.com
Features
The iT3010 is a packaged differential amplifier designed for use in 10.7 Gb/s and 12.5 Gb/s
(OC-192) optical transmitters and receivers as a gain stage with limiting functionality. It allows
single-ended input signals from 350 mVpp up to 900 mVpp, or differential signals from 250
mVpp to 1800 mVpp to be limited at a constant differential output voltage of 3.8 Vpp. The
iT3010 can be used as predriver for OC-192 optical modulator driver amplifiers. Output voltage
control and external offset correction are provided. The amplifier also provides excellent linear
performance when operating at lower output voltage. Both AC and DC input coupling are
allowed. DC-coupled SCFL differential input (input HIGH voltage = 0 V, and input LOW voltage
= -900 mV) are allowed.
