SAA7135 Datasheet, PDF (1/6 Pages) NXP Semiconductors – Single-chip, analog TV video/stereo DECODER

SAA7135
Single-chip, analog TV video/stereo
decoder for worldwide PCI applications—
with Dolby Pro Logic
For multi-standard analog and hybrid TVs, the Philips
SAA7135 integrates high-quality decoding of all analog
video and stereo formats used in TVs worldwide. It
gives manufacturers a low-BOM solution for new PCI
products, and an efficient upgrade path for adding
advanced audio features to existing SAA713x designs.
Semiconductors
Like other SAA713x single-chip TV decoders, the SAA7135 offers
high-quality detection and decoding of all worldwide analog TV
video standards. In addition, it decodes all worldwide TV stereo
formats and supports advanced audio features, such as Dolby Pro
Logic decoding, and more. The SAA7135’s flexible design, reusable
components, and versatile external interfaces lower BOM and cost
and support advanced TV decoder configurations. It gives manufac-
turers an ideal solution for adding robust multi-standard analog TV
decoding to a wide variety of computing and consumer products.
In addition, the SAA7135’s 100% pin compatibility with existing
SAA713x decoders enables efficient reuse of existing SAA713x
designs for more sophisticated markets or price points.
Key features
> Fully automatic standard detection and decoding of worldwide
analog TV video formats (PAL, NTSC, and SECAM), and world-
wide TV stereo formats (A2/Dual-FM, NICAM, BTSC with dbx^™,
SAP, EIAJ, and FM radio)
> Advanced audio feature processing including Dolby^® Pro Logic^™,
Virtual Dolby Surround^™, Philips Incredible Sound, and more
> Supports simultaneous stereo decoding and adaptive 3D comb
filtering (to enhance picture quality)
> Certified three-level Macrovision^® detection circuitry
> Captures raw VBI data (for Closed Captioning,Teletext, etc.)
> Superior subpixel-accurate horizontal and vertical scaling
> Outputs digital I²S audio and ITU-656 video
> Captures transport streams from digital TV broadcasts and
MPEG datastreams in time-shift applications
> For PCI (Rev. 2.2, ACPI compliant) and standalone configurations
The SAA7135 delivers exceptional picture quality and advanced
video features proven in other SAA713x devices: low-noise, high-
quality ADCs, an adaptive comb filter, and subpixel-accurate scaling.
Certified three-level Macrovision detection circuitry ensures the
video content’s original analog copy protection remains intact.
Capture of transport streams from all digital TV broadcast standards
supports hybrid TV designs; capture of MPEG datastreams from
MPEG encoders supports time-shift applications. In PCI configura-
tions, the SAA7135 takes full advantage of the streaming capabilities
of PCs by outputting decoded video, audio,VBI, and transport
streams through DMA bus-mastered writes across the PCI bus.
Target applications
The SAA7135 is targeted for adding multi-standard analog TV
decoding with robust audio features to computing and consumer
products such as desktop and portable PCs, hybrid TVs or set-top
boxes (cable, terrestrial, satellite), personal video recorders (with
time shifting), DVD recorders, and more.
