iT3010E
10GHz Medium Gain Amplifier
Applications
The iT3010E is a RoHS-6-compliant packaged
differential amplifier designed for use in
10.7Gb/s and 12.5Gb/s (OC-192) optical
transmitters and receivers as a gain stage with
limiting functionality.
•
•
•
The iT3010E allows single-ended input signals
from 350 mVpp up to 900 mVpp, or differential
input 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. DCcoupled SCFL differential input (input HIGH
voltage = 0 V, and input LOW voltage = -900
mV) are allowed.

General Description
iT3010E
10GHz Medium Gain Amplifier
Exceeding the maximum ratings may cause damage to this product or lead to a reduction in reliability. These are
solely stress ratings and functional operation of the device at these or any conditions beyond those indicated in
recommended-operating-conditions(pg2) is not implied. Exposure to absolute-maximum-rated conditions (pg 2)
for extended periods may affect device reliability. Not following the biasing sequence in operating-setup (pg 9)
may damage the device.

Marking Information
iT3010E
10GHz Medium Gain Amplifier
CAUTION: APPLICATION
•
•
•
Do not exceed junction temperature of 150C. A heat sink and low impedance thermal path is
required.
RF Microwave devices are capable of high energy densities at the RF output; user application
may be required to meet SAR (Specific Absorption Rate) regulatory safeguards.
This is an extremely fast high bandwidth digital device capable of high level harmonic emissions
that are normal components of a high fidelity pulse. Care may be required to meet regulatory
intentional or unintentional system emission requirements.
CAUTION: ESD-SENSITIVE DEVICE
•
•
•
Less than 250V HBM ESD discharge may damage the device.
Class 0 Device, JESD22-A114E
These are ESD sensitive devices and should be handled with appropriate precaution including
the use of wrist-grounding straps.
CAUTION: THIS PRODUCT CONTAINS ARSENIC (As)
•
•
This product contains Arsenic.
Avoid ingesting, fracture, burning or chemical treatment of the product.

Description
Objective datasheets are issued during the design stage of a new product introduction
and contain the product’s target design parameter specifications. The parameters are
generally only specified for typical operation. PCNs are not issued for objective datasheet
revisions.
Advanced datasheets are issued during the product development stage of a new product
introduction and contain the product’s target design parameter specifications as well as
measured results from DVT. Parameters are generally only specified for typical operation
and some important design min/max parameters will be specified. PCNs are not issued for
advanced datasheet revisions.
Production datasheets are issued once the product has passed the reliability assessment
(qualification) and production device characterization stage of a new product introduction
and will contain the product’s design parameter specifications as well as measured results
from DVT and product characterization. Parameters are generally specified with min/max
parameters. PCNs are issued for production datasheet revisions if required.
