Single-chip controllers enable advanced STB products
IBM STB03xxx digital set-top box inte-grated controllers provide single-chip,high-performance solutions for digital video broadcasting (DVB), digital record-ing, and demanding video delivery applicat
ions, including interactive Web browsing. New members of IBM’s family of STB products, these advanced controllers incorporate an IBM PowerPC 405TM
processor within IBM’s STB architecture.Featuring IBM Blue Logic TM  technology and manufactured using IBM’s advanced 0.25-micron process, the STB03xxx controllers incorporate four powerful subsystems — processor , digital audio/video, peripheral and memory interface.The efficient STB03xxx controller design makes more MIPS available to STB
manufacturers by allowing the base audio and video decoding activities to execute with minimal host processing. A unified memory architecture provides configura-
Highlights
tion flexibility . The advanced features of STB03xxx controllers include:•Integrated PowerPC 405 processor •MPEG-2 audio/video decoder
•Dolby ® Digital audio decoder option*(IBM STB0321x and STB0341x only)•MPEG-2 transport demultiplexer •On-screen display controller •NTSC/P AL digital encoder
•IDE interface for hard disk drive (HDD),smart card, parallel and serial ports Design flexibility supports div erse applications
Designers have the flexibility to choose from a range of STB03xxx controllers to satisfy their individu
al application requirements. They can choose a
controller with an embedded PowerPC 405 featuring either 150-MIPS or 225-MIPS performance. In addition, they have the flexibility to select a controller with Macrovision Copy Protection  support,Dolby Digital audio support or both. The new IDE interface and anti-flicker-filter feature allow easier enablement of digital video recording and Web browsing applications.
PowerPC 405 deliv ers high performance
decoderThe PowerPC 405 processor , the heart of the  processor subsystem , features high-speed operation at 108 MHz or 162 MHz,a 16-KB instruction cache and an 8-KB data cache to enhance overall applica-tion performance. With this processing capability , products can support elec-tronic programming guides, e-commerce applications, Web browsing and other interactive applications.
Digital audio and video capabili-ties support next-generation applications
The digital audio and video subsystem delivers high-quality video and sound,enabling service providers to offer
graphically rich user interfaces for next-generation interactive applications. The digital audio and vide
o subsystem incorporates:
• MPEG-2 video decoder with anti-flicker filter and five on-screen display (OSD)/video planes; decodes MPEG-2 Main Profile at Main Level (MP @ ML) video • MPEG-2 transport and DVB descrambler • MPEG-2 audio decoder; decodes MPEG-2 Layer I & Layer II (CD quality)audio
• Dolby Digital-compliant decoding (IBM STB03x1x controllers only; a Dolby Digital license is required)
• Digital encoder , including NTSC/P AL
analog conversion, six concurrent analog video outputs and compatibility with SCART connectors
STB03xxx controllers provide single-
chip, high-performance solutions.
• Macrovision Copy Protection support (STB03xx1 controllers only; note: a Macrovision license is required)• Audio PLL
Choose from a wide range of peripheral and memory inter-faces
The peripheral interface subsystem provides the range of interfaces design-ers need to meet customer requirements:• General purpose timers, pulse width modulation (GPT , PWM)
• IEEE 1284 peripheral interface • T wo Smart Card interfaces (SCIs)• T wo inter-integrated circuit (I 2C) inter-faces
• UART interface (16550)
• Serial and infrared communications controller (SICC)• Serial control port • Modem I/F
• General purpose input/output (GPIO)controllers
