MC44C404

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 Companding Audio Multiplex 728 (NICAM) stereo encoder. Intended for use in set-top boxes, VCRs, DVD players/recorders, game www.datasheet4u.com 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 compliance 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 mW RoHS compliant MC44C404 NICAM STEREO ENCODER EP SUFFIX 32-LEAD TQFN PACKAGE CASE 1457-01 Benefits Preservation of original surround sound fidelity Multi standard Low system component 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-ch...
