Iterra iT3012

The iT3012 is a packaged differential-to-single-ended amplifier designed for use as an optical modulator predriver with limiting functionality in 10.7 Gb/s and 12.5 Gb/s (OC-192) optical transmitters and receivers. It allows single-ended input signals of 350 mVpp to 900 mVpp or differential signals of 250 mVpp to 1800 mVpp to be limited at a constant single-ended output voltage of 1.9 Vpp. It provides output voltage control and allows external offset correction.

DESCRIPTION

iT3012 also provides excellent linear performance when operating at lower output voltages. Both AC and DC input coupling are allowed. DC-coupled SCFL differential input (input “high” voltage = 0 V, input “low” voltage = -900 mV) is allowed.
