SAA7135 Datasheet, PDF (5/6 Pages) NXP Semiconductors – Single-chip, analog TV video/stereo DECODER

per DMA channel allows system designers to tailor and balance
the latency behavior for each channel in a given application,
adapting to actual conditions.
Comprehensive software support and reference design
The SAA7135 software development kit (SDK) supports a com-
mon code base for VfW and Windows Driver Model (WDM)
architectures, reducing software maintenance and protecting
software investments. The SDK is based on a Component Object
Model (COM) interface; it includes sample code in Visual Basic
and C++ and a description of the interface.
SAA7135 WDM driver support is provided for all DirectShow^®-
based applications. A WDM device driver kit (DDK) includes a
plug-and-play driver, capture-driver installations, and documenta-
tion.The SAA7135 WDM driver is WHQL validated and is
supported for Windows^® 98/ME/2000/XP. The SAA7135 VfW
driver is available for Windows 95/NT4. A BDA-compliant driver
is included for digital TV applications. The SAA7135 also provides
a custom API enabling development of specialized applications
when published Windows APIs (WDM or VfW) are insufficient.
A comprehensive SAA713x Reference Design Kit enables system
designers and hardware manufacturers to quickly evaluate
SAA7135 features and develop single, half-size PCI designs for
hybrid TV receivers.The Kit includes:
> a reference PCI card with SAA7135 decoder, analog TV tuner,
32.11-MHz quartz crystal, I²C EEPROM
> a board connector plate with TV connector, CVBS and S-Video
inputs, audio input (line-in) and output (line-out)
> an optional voltage regulator for improved video performance
> the SAA7135 SDK and DDK
> installation and user guides
> board design, schematics, and Gerber files
> video cables
