iT3012
8 GHz, Differential-to-Single-Ended Amplifier
Description
www.DataSheet4U.com
Features
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.
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.
Limiting function with 1.9 Vpp single-ended output
3 dB bandwidth: 8 GHz
Single-ended Gain: 17.5 dB
Standard bias supply levels: -5 V or -5.2 V, +5 V
Power consumption: 665 mW
Low group delay and jitter
