Sony has now released XarinaTM "CXD4135GG and CXD4235", system ICs that integrate image signal processing (ISP) and video
encoding for the next generation of IP surveillance cameras.
Supporting a wide range of CCD and CMOS image sensors in industrial applications, the CXD4135GG and CXD4235 come with
wide dynamic range (WDR), motion detection, face detection and other intelligent functions to enable high picture quality and
high value adding in camera signal processing.
To build H.264 encoder, Ether MAC, SD Card interface and other peripheral functions in the ICs reduce system costs, minimize
the need for external components and make possible IP cameras for a wide range of functions.
■ H.264 encoder (1080p / 60 frame/s)
■ Video Analytics engine
■ Multi-streaming (4 streams)
■ Wide dynamic range (120 dB)
■ Supports a wide range of image
sensors (CMOS/CCD)

enable ideal ICs and effective development
to create imaging devices for the network
age.
High Picture Quality and High
Frame Rate
In the surveillance camera market, the
demand for IP network camera systems has
gradually increased over the years.
The CXD4135GG and CXD4235 are system
ICs that combine image signal processing
(ISP) with video encoding. The ISP unit
features the latest WDR functions, noise
reduction (3D-NR /2D-NR) and other
functions to create cameras with high picture
quality.
The ICs also support H.264 and Motion JPEG
video encoding to enable video streaming at
up to 1920 × 1080p at a high frame rate of
60 frame/s.
Supports a Wide Variety of
Image Sensors
The CXD4135GG and CXD4235 support the
"EXview HAD CCD II"*1 ICX692AKA*2, a
highly sensitive complementary color CCD
image sensor for our industrial applications
and "Exmor"*1 IMX140LQJ*3, a full HD 60
frame/s CMOS image sensor. One platform
allows customers to build the type of cameras
(for example, a WDR model, high-sensitivity
model, a Day&Night model, etc.) they desire.
(See table 1.)
Sony plans to support an even wider range of
image sensors.

Intelligent Functions
- Motion detection
- Face detection
- Tampering alarm
- Digital image stabilizer
The ICs come with these and many more
image analysis functions to enable high value
added image processing.
Use of an external FPGA will further extend
functionality to enable use as a traffic
surveillance system.
User-Friendly Development
Environment
The lineup includes a package type IC
(CXD4135GG) and a modular type (CXD4235)
that contains DDR3 memory for image and
other processing to simplify board design and
reduce product footprint.
To help customers effectively develop
camera systems, Sony provides a software
development environment (evaluation boards,
reference design and sample applications) and
picture quality adjustment tools. These tools
facilitate the development of surveillance
cameras with high picture quality and high
added value as well as the building of largescale network camera equipment.
Our goal was to develop ICs compatible
with a wide range of image sensors
through mobilizing the experience and
exper tise of the entire development
team. High quality signal processing
acquired in the pursuit of camera IC
technology and intelligent functionality
that provides high added value made it
possible for us to produce an IP camera
system IC compatible with multiple
applications.
Be sure to consider “Xarina” in your next
IP camera solution.
