Analog Front End IC and Camera System IC
for Security Cameras
CXD5148GG,
CXD4140GG
Sony has developed the CXD5148GG, a new analog front end (AFE) IC, and the CXD4140GG, an "Enhanced Effio-E" IC, both for
security camera application.
The CXD5148GG has been developed as a common*1 AFE for the "Effio" series enabling the sharing of boards for greater user
friendliness.
The CXD4140GG "Enhanced Effio-E" is an improved version of the CXD4127GG
"Effio-E" *2 and also provides a new infrared LED
exposure optimization function and capability to customize part of the On Screen Display (OSD) menu.

 Use of Common Boards |
|
The CXD5148GG is an AFE for CCD image
sensors equipped with a CDS, a timing generator
and V and H drivers.
The new product supports a wide range of
driving frequencies as well as single and
double exposure operating systems to enable
connection to all CCD image sensors used
by the System IC "Effio" series for security
cameras.
The CXD5148GG camera IC supports
the newly added "Enhanced Effio-E"
(CXD4140GG) as well as the "Effio-P"
(CXD4129GG)*3 and the "Effio-S"
(CXD4130GG)*3. (See figure 1.)
The "Effio" series required that either the
CXD4813GG or the CXD4816GG*2 AFE be used depending on the CCD image sensor
and the system IC. The CXD5148GG allows
use of common boards simplifying the configuration
of camera lineups.

| Striving for Greater Ease of Use |
|
The CXD5148GG provides greater performance
than the current Sony products while
also streamlining board design.
Optimization of pin functions that reduce
pin numbers, the adoption of a new generation
of processing technology and turning
high-voltage processes into a single chip have
all helped to lower power consumption. (See
table 2.)
Like the current Sony products, the
CXD5148GG can obtain the required power
supply voltages from outside by the integration
of an LDO to handle the multiple supply
voltages that the adoption of a new generation
of processing technology requires.
Processing technology and hardware circuit
design have removed the restrictions in supplying
power to components requiring different
voltages, for example, between 1.8 V
and 3.3 V systems and between VH and VL thereby simplifying the design of power supplies
and reset circuits for camera systems. |
| Function for Optimizing
Exposure for Infrared LEDs |
|
"Enhanced Effio-E" (CXD4140GG) is an
improved version of "Effio-E.
"The new product comes with a function for
optimizing exposure under infrared LED
illumination to make it compatible with the
currently popular infrared LED security cameras.
This function ensures correct exposure and
increases visibility by preventing the overexposure
that the excessive front lighting of a
highly directional infrared LED light source
often causes during nighttime photography.
(See photograph 1.) |
| Some OSD Menu Functions can
be Customized |
|
The OSD for setting up the camera consisted
of a fixed menu in "Effio-E" that could not be
customized. For a greater ease of use, some
OSD menu functions can now be customized
by the user.
This new capability allows customers to edit
the menu structure and function names that
appear to suit camera specifications. (See
table 1.) |

We were able to integrate two types of
AFEs to maintain connectivity with a lot
of CCD image sensors and multiple chips
and cut no corners in ensuring that the
new product delivered better performance
than current products.
Sony has already received inquiries from
many customers.
We are confident that the new AFEs, the
"CXD5148GG" and the "Effio" series, are
the best choice you can make. |
