Analog TV video and stereo decoder for
computing and consumer applications in
North America and Japan
On a single chip, the SAA7173 TV video/stereo decoder handles
fully automatic detection and decoding of all worldwide analog TV
video standards and the TV stereo formats used in North America
and Japan. It delivers exceptional picture quality and advanced video
features: low-noise, high-quality ADCs, an adaptive comb filter, sub-
pixel-accurate scaling, and certified three-level Macrovision detection
circuitry. The SAA7173’s flexible design, reusable components, and
versatile external interfaces lower BOM and cost and support
advanced TV decoder configurations.
Target applications
The SAA7173 is a space-efficient solution for adding high-quality
multi-standard analog TV decoding to a wide variety of computing
and consumer products. Its 100% pin compatibility with the Philips
SAA7174 decoder enables efficient reuse of SAA7174 designs.The
SAA7173 is targeted for products in North American and Japanese
markets such as desktop and portable PCs, personal video recorders
(with time shifting), hybrid (analog/digital) TVs and cable, terrestrial,
and satellite set-top boxes, USB/1394 video dongles, DVD recorders,
and more.
