CX25836/7
high performance in a small package
Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The CX25836/7 is Conexant’s fourth-generation video decoding
solution. It provides a highly integrated single-chip analog video capture
solution ideal for a wide range of digital video systems applications.
The CX25836/7 features, although applicable to a wide range of analog video
applications, are focused on both the security and consumer electronics
markets. Most notably, CX25836’s fast camera locking capabilities and flexible
programmable inputs make it most suitable for the security camera market.
The CX25837 with its ability to decode Composite Video Baseband Signal
,
(CVBS), S-Video, and YPbPr, is best suited to address the wide array
of consumer electronics requirements. Both devices are distinguished by high
quality, flexibility, integration, and ease of use. Both fit into a wide array of
applications: set-top-boxes, flat panel displays (such as LCD and Plasma TVs),
HDTVs, and PVRs/DVRs.
High Quality
The CX25836/7 integrates two high-performance 10-bit ADCs and provides a
full 10-bit data path through the video decoder to maintain optimum end-to-
end video quality. Eight video inputs provide flexible analog muxing that can
be configured for any of the following:
• Eight CVBS inputs
• Four Y/C inputs
• Three composite with one Y/C and one YPbPr
• One composite with two Y/C and one YPbPr
• Two composite with two YPbPr (CX25837 only)
The CX25837 uses its high quality Analog-to-Digital Converter (ADC) to
sample the YPbPr video format, which is most often found on prosumer
(intermediate to advanced end user) type equipment. Simultaneous
digitization of Pb and Pr, through the 10-bit chrominance A/D, is used to
offer this feature cost effectively yet yield the highest quality.
