| SGTV58XX PRODUCT BRIEF A COMPLETE AUDIO SOLUTION FOR TELEVISION The SigmaTel SGTV58XX is a family of TV audio processors designed to serve as an audio solution for analog TVs, digital TVs, and hybrid (analog/digital) TVs worldwide. Other applications include set top boxes or other designs where a low cost, high fidelity audio processor is required. The SGTV58XX simplifies TV audio design by integrating a demodulator, digital I/O, analog I/O and audio processing in one part. The SGTV58XX family is designed for integration into any TV including LCD, plasma, rear projection and CRT TV's. SIGMATEL SGTV58XX COMPETITIVE EDGE * Lower bill of materials (BOM) costs through integration * Design flexibility for simplified system design * Integrated features reduce implementation costs for large TVs while providing a cost effective solution for small TVs INTEGRATION REDUCES BILL OF MATERIALS (BOM) COST * Demodulator supports all worldwide standards, including NICAM, EIAJ, A2 and BTSC * Ten stereo analog input switch eliminates need for external switch * SPDIF transmitter * Digital input and output sample rate converters for direct connection to HDMI with no external components * Multiple digital I/O paths improve system routing and allow audio processing and sync delay in other parts of system to be utilized * Integrated Sync Delay (optional) * Headphone drivers * Subwoofer output SIGMATEL SGTV58XX ADVANTAGES * Proven analog performance with SigmaTel DACs and ADCs * 24-bit digital I/O * Support for simultaneous routing of multiple audio streams * Digital processing for added value and product differentiation * One audio design system can support entire TV product line MIXED -SIGNAL MULTIMEDIA SEMICONDUC TORS SGTV58XX PRODUCT BRIEF SPECIFICATIONS DEMODULATOR * Two analog SIF inputs with automatic gain control * Stereo demodulation of TV-sound standards worldwide - BTSC - EIAJ - NICAM - A2 * Automatic standard selection * Automatic sound selection * Automatic mute * Post processing - Alignment free DBX compatible Digital Noise Reduction - De-emphasis ANALOG I/O * Ten analog stereo input pairs - SCART compatible * Main analog stereo output with separate main subwoofer output * Stereo headphone output * Three SCART compatible outputs DIGITAL AUDIO PROCESSING * Tone controls * Loudness * Automatic volume correction (Compressor) * Parametric Equalizer/Graphic Equalizer * Peak detection * 100mS Audio Sync Delay * SRS WOWHDTM * BBE High Definition SoundTM DIGITAL I/O * 24-bit digital I/O with rates up to 48kHz for synchronous inputs and 96kHz for asynchronous sample inputs * Two synchronous I2S inputs * One asynchronous I2S input with sample rate conversion * Two synchronous I2S output channels * One asynchronous I2S output with sample rate conversion and video synchronization * SPDIF transmitter * Flexible routing - any input can be routed to any or multiple outputs and multiple concurrent channels can be supported at one time CONTROL * I2C * Three GPIO, one programmable as an interrupt PACKAGE - 100 PIN TQFP www.sigmatel.com -- tel: (512) 381-3700 -- TVaudio@sigmatel.com March 13, 2006 Copyright (c) 2006 SigmaTel, Inc.
