MC44C404 Datasheet | Freescale Semiconductor

Freescale Semiconductor Advance Information Document Number: MC44C404 Rev. 0.3, 11/2007 NICAM 728 - Stereo Encoder The MC44C404 NICAM Stereo Encoder is the industry’s first single-chip CMOS implementation of a Near Instantaneous panding Audio Multiplex 728 (NICAM) stereo encoder. - Intended for use in set-top boxes, VCRs, DVD players/recorders, game .. stations, and other applications that are required to output high-quality stereo sound through a single RF coaxial cable. - Engineered to process analog audio signals to generate a QPSK modulated signal in pliance with the EN 300 163 standard. - Designed to output this signal to a Freescale RF modulator, which in turn produces a stereo encoded RF channel for use with any NICAM stereo television receiver. Features - - - - - - - Supports B, G, H, I, K1, L system standards NICAM digital audio processing encodes and transports stereo signals Integrated A/D converter input and D/A converter output circuitry Extended low frequency response (below 25 Hz) Simple passive interface to MC44BS373/4 UHF modulators Low power consumption - typically < 50 m W Ro HS pliant NICAM STEREO ENCODER EP SUFFIX 32-LEAD TQFN PACKAGE CASE 1457-01 Benefits - Preservation of original surround sound fidelity - Multi standard - Low system ponent count, small board size and significantly low overall system cost - No manual alignment of filters or phase controls Reference Documentation NICAM 728: Transmission of two-channel digital sound with terrestrial television systems B, G, H, I, K1 and L.
