iT3010E
10 GHz Medium-Gain Differential Amplifier
Description
The iT3010E is a RoHS-6-compliant 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 iT3010E 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.
