Single-Chip Broadcast Audio/Video Decoder
CX25840/1/2/3
Highly Flexible Single-Chip Video and Broadcast
Audio Decoding
Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The CX25840/1/2/3 is Conexant’s second generation of Audio/Video
(A/V) decoders built on the success of the CX23880 family of broadcast
A/V PCI decoders. These devices are optimized for the regional broadcast
requirements and are pin-to-pin compatible with each other. The CX25840/
1/2/3 is the smallest integrated stereo broadcast A/V decoder capable of
demodulating all of the most common worldwide A/V standards.
The CX25840 with no DBX and CX25841 with DBX support both the North
American (BTSC) and Japanese (EIA-J) markets, respectively. The CX25842
supports the European market. And finally, for the customer who wants
a single chip to address all worldwide broadcast standards, there is the
CX25843. This device provides highly integrated, single-chip analog, A/V
capture solutions ideal for digital video systems that support worldwide
broadcast analog A/V content.
Distinguished by its high quality, flexibility, broadcast audio support, integration,
and ease of use, the CX25840/1/2/3 can be designed into a wide array of
applications, including set-top boxes, flat panel displays, HDTVs, and personal
video recorders (PVRs).
Highly Integrated
The CX25840/1/2/3 is highly integrated, and includes anti-aliasing, noise
rejection filters, and Automatic Gain Control (AGC) and DC restore circuits.
Along with worldwide decoding for all common video and broadcast audio
standards, processing functions such as high-quality four-lines adaptive
comb filtering, arbitrary horizontal and 5-tap vertical scaling, hue, brightness,
saturation, and contrast controls are also included. The audio path includes
an automatic volume control function and two assignable stereo processing
units for control of volume, three-band equalization, and balance.
The level of audio and video integration provided by the CX25840/1/2/3
removes the need for additional broadcast audio decoding and processing
chips or external sound demodulation chips. It also reduces the overall
Bill-of-Materials (BOM) for the system developer, without compromising
audio and video performance.
