µPC3211GR
AGC AMPLIFIER FOR DIGITAL CATV RETURN PASS
DESCRIPTION
The µPC3211GR is a silicon monolithic integrated circuit designed as AGC amplifier for digital CATV systems. This
IC is the AGC amplifier with 55 dB gain control range which is packaged in 20-pin SSOP. The device is able to use
for digital QPSK system, therefore it contributes to make design of transmission system simplicity.
FEATURES
• Wide gain control range
55 dB TYP.
• Low distortion
IM3 = 57 dBc TYP. @Pout = −10 dBm
IM2 = 44 dBc TYP. @Pout = −10 dBm
• Supply Voltage
9V
• Packaged in 20-pin SSOP suitable for high-density surface mount.

rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other

• Descriptions of circuits, software, and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these circuits,

• While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
• NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
