STI3520 MPEG AUDIO / MPEG-2 VIDEO INTEGRATED DECODER APPLICATIONS DBS RECEIVER DIGITAL TV RECEIVER DIGITAL CABLE TV RECEIVER . . . . . . . . . . . . . . BRIEF DATA SINGLE CHIP COMBINING THE DECODING FUNCTIONS OF THE STi3500A VIDEO DECODER AND THE STi4500 AUDIO DECODER ON-CHIP PLL ALLOWING FULL CHIP OPERATION WITH TWO EXTERNAL CLOCKS VIDEO DECODER FULLY SUPPORTS MPEG2 MAIN PROFILE/MAIN LEVEL (MP@ML) AUTOMATIC VIDEO ERROR CONCEALMENT ENHANCED ON-SCREEN DISPLAY GENERATOR : 16 COLORS/REGION, LINKED LIST MEMORY MANAGEMENT AUDIO DECODER SUPPORTS LAYERS I & II OF MPEG ALL POPULAR PCM AUDIO OUTPUT FORMATS SUPPORTED STANDARD 8-BIT INTERFACE FOR MICROCONTROLLER AND COMPRESSED DATA INPUT SUPPORT FOR SYNCHRONOUS DRAM 3.3VPOWER SUPPLY I/Os 5V TTL COMPATIBLE , 0.5m CMOS TECHNOLOGY The STI3520 requires minimal support from an external microcontroller, which is mainly required to initialise the video decoder at the start of every picture. Separate audio and video data streams are input through the 8-bit data port. Time stamps are detected and made available to the microcontroller for the managementof audio/videosynchronization. User-defined bitmaps may be superimposedon the displayed picture through use of the on-screen display function. These bitmaps are written directly into the DRAM memory by the microcontroller. Undetected bitstream errors which would cause decoder errors activate the error concealment functions. DESCRIPTION The video decoder is a real-time video decompression processor supportingthe MPEG-1 and MPEG2 standards at video rates up to 720 x 480 x 60Hz or 720 x 576 x 50Hz. Picture format conversion for display is performed by a vertical and a horizontal filter (sample rate converter). External DRAM, typically of size 16 Mbits is required. The audio decoder is compliant with layers I and II of the MPEG standard. Sampling rates of 32, 44.1 and 48kHz can be used. This specification refers to versions 3.1 or later (marking CB or higher). PQFP160 (Plastic Quad Flat Pack) ORDER CODE : STI3520CV October 1996 This is advance information on a new product now in development or undergoing evaluation. Details are subject to change without no tice. 1/1 |
