SAA7135

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.

Single-chip, analog TV video/stereo

decoder for worldwide PCI applications—

with Dolby Pro Logic

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.

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

Dolby

Pro

Logic

™

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.

Incredible Sound, and more

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

Virtual Dolby

Surround

™

, Philips

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 I

S 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

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.
