| PRODUCT INFORMATION AVF 49xyA MULTIMEDIA Jan/2004 AVF 49xyA Audio/Video Front-End The AVF 49xyA is a fully integrated AudioVideo Front-end solution specifically well suited for DVD recorder and personal video recorder (PVR) applications. It combines the functional units of both a Multistandard Sound Processor (MSP) and a Video Pixel Decoder (VPX) and it provides the audio/ video synchronization of the output signal. The AVF 49xyA comes in a PQFP128 package. The MSP unit covers the sound processing of all analog TV standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing - starting with analog sound IF signal input down to processed analog AF signal output - is performed. The VPX unit provides the full-feature video acquisition for consumer and multimedia applications. All of the processing capability necessary to convert an analog video signal in CVBS, Y/C or YCrCb format into a digital component stream is integrated. Additionally, text slicing for Intercast, Teletext, and Closed Caption is provided. For improved Y/C separation, an adaptive 4H comb filter is included. General Features I2C interface with different device addresses for using two AVF 49xyA in one system Audio / video synchronization either in Master or Slave mode PQFP128-2 package Dual-window cropping and scaling Horizontal resizing between 32 and 864 pixels/line High-quality anti-aliasing filter Scaling controlled peaking and coring Digital YCrCb 4:2:2 format ITU-R 601/656 compliant output format Square pixel format (640/768 pixels/line) 8-bit or 16-bit synchronous output mode Video Features High-performance adaptive 4H comb filter Y/C separator with adjustable vertical peaking Multistandard color decoding: - NTSC-M, NTSC-443 - PAL-BDGHI, PAL-M, PAL-N, PAL-60 - SECAM, S-VHS Video ADCs with clamping and automatic gain control (AGC) Seven analog inputs with integrated selector for the following sources: - 4xcomposite video (CVBS), or - 2xCVBS and 2 xY/C (S-VHS), or - 2xCVBS, 1xY/C and 1xYPrPb Decoding and detection of full Macrovision 7.01 protected video 13.5 MHz/16-bit and 27 MHz /8-bit output rate VBI bypass and raw ADC data output High-performance hardware data slicing Multistandard data slicer - NABTS, WST - CAPTION (1x, 2x), CGMS, VPS, WSS, Antiope Full support for - Teletext, Intercast - WebTV for Windows, EPG services VBI and Full-field mode Data insertion into video stream Simultaneous acquisition of Teletext, VPS, WSS, and Caption PRODUCT INFORMATION AVF 49xyA Audio Features Standard selection with single I2C transmission Automatic standard detection of terrestrial TV standards Automatic sound selection (mono/stereo/bilingual), new registers MODUS, STATUS Sound IF (SIF) input Automatic-carrier-mute function Interrupt output programmable (indicating status change) Main/Aux channel with volume Automatic volume correction (AVC) Two channel mixer Selectable preemphasis for Aux channel Four stereo Line inputs, two stereo Line outputs Complete Line in/out switching matrix Two 48-kHz I2S inputs; one asynchronous 5 ... 50-kHz I2S input, one asynchronous I2S output All analog Mono sound carriers including AM-SECAM All analog FM-Stereo A2 and satellite standards All NICAM standards Jan/2004 Simultaneous demodulation of (very) high-deviation FM-Mono and NICAM Demodulation of the BTSC multiplex signal and the SAP channel Alignment-free digital DBX noise reduction for BTSC Stereo and SAP BTSC stereo and EIA-J separation significantly better than spec.
