The Type 1/3 CCD has become the main optical system used in surveil-
lance cameras, and is expected to remain an important device in this
area for the foreseeable future.
Sony has adopted its unique Super HAD CCD technology and a new
structure technology in these new Type 1/3 CCD products, and has
significantly improved the sensitivity and smear characteristics over
those of conventional products such as the ICX054/055BK/BL and ICX058/
059CK/CL.
These new products, the ICX404/405/408/409AK/AL, can improve both
the sensitivity and the image quality of existing user products since they
can directly replace conventional products.
These new products also feature adjustment-free circuits for externally
applied voltages, and thus can contribute to reducing parts counts in
the drive circuit.

The ICX404/405/408/409AK/AL are
diagonal 6 mm (Type 1/3) 250K/290K/
380K/440K-pixel CCD image sensors
positioned as follow-on devices to
Sony’s conventional ICX054/055BK/
BL and ICX058/059CK/CL CCDs.
These new products specifically aim at
providing higher image quality, which
is particularly desired by our custom-
ers, and achieve significant improve-
ments in both sensitivity and smear over
conventional products. (See tables 1 to
4.) While the Sony ICX254/255/258/
259AK/AL EXview HAD CCDs, which
feature sensitivity that extends into the
near infrared wavelength region, are
appropriate for imaging applications
VOICE
The introduction of the latest
technologies has allowed us to
achieve CCDs that significantly
surpass the characteristics of
conventional Type 1/3 CCDs. We
are convinced that these CCDs
can respond to your needs. We
hope you will verify their super-
lative characteristics through
your customers’ eyes.
under low-light conditions, the ICX404/
405/408/409AK/AL are appropriate for
use in surveillance cameras and other
products for general-purpose products.
(See figure 1.)
High Sensitivity
The Type 1/3 CCDs of this release
(ICX404/405/408/409AK/AL) feature
sensitivity characteristics improved by
between approx. +4 and +6 dB over
Sony’s conventional products (ICX054/
055BK/BL and ICX058/059CK/CL).
These products can demonstrate their
performance in surveillance applica-
tions in particular, since such applica-
tions require use in low-light environ-
ments. (See photograph 1.)
Low Smear
The CCDs of this release adopt a new
structure technology that makes the
insulation film between the electrodes
and the substrate even thinner, and that
achieves a large improvement in the
smear characteristics. These CCDs
reduce smear by –15 to –20 dB and
achieve the low smear level of –110 dB
or better. (See photograph 2.)
High Saturation Signal
As compared to conventional products
(ICX054/055BK/BL and ICX058/
059CK/CL), these CCD features a satu-
ration signal level improved by approx.
+2 to +3 dB in the 250K-pixel products
and approx. +4 to +5 dB in the 380K-
pixel products. This higher sensitivity
and higher saturation signal allow these
CCDs to contribute to improved image
quality in end products.
Easy Replacement of
Conventional Products
The image sizes, pixel counts, and pack-
ages used in these new CCDs are all
identical to the corresponding conven-
tional Sony CCDs (ICX054/055BK/BL
and ICX058/059CK/CL). In the pin
configuration, special efforts were made
to keep the changes to the substrates of
the conventional products to an abso-
lute minimum. Furthermore, external
applied voltages were made adjustment
free, allowing the number of external
components to be reduced from that in
current end products.
