MSP 3402C Short Information MSP 3402C Sound Processor for Korea (68-Pin PLCC Package, 64-pin PSDIP Package, or 52-pin PSDIP Package) The MSP 3402C is designed as a single-chip sound processor for applications in analog and digital TV sets, satellite receivers, video recorders, and PC-cards for Korea. The MSP 3402C increases function integration in a spectacular way. The chips are produced in submicron CMOS technology and will offer a wide range of interesting features combined with high performance digital signal processing. The complete TV-sound-processing, starting at the Sound-IF domain, will be performed by one single IC. The IC’s input signal consists of analog audio signals in baseband and at intercarrier position. The MSP 3402C covers the sound processing of the TV-standard M. The MSP 3402C is fully backwards compatible to the MSP 3410B/D, which include NICAM sound decoding. The MSP 3402C offers the following advantages: – two selectable analog inputs – Automatic Gain Control (AGC) for analog input: input range: 0.14 – 3 Vpp – Sound-IF frequency 4.5 MHz and 4.7242 MHz – integrated A/D converter – all demodulation and filtering is performed on chip and is individually programmable – no external filter hardware is required – only one crystal clock (18.432 MHz) is necessary – FM carrier mute function – flexible selection of audio sources – digital input and output interfaces via S-Bus for D2MAC, and via I2S-Bus for external DSP-Processors featuring Surround Sound etc. – digitally performed FM-identification decoding and dematrixing for Korea 2-tone system – digital baseband processing: volume, bass/treble or 5 band graphic equalizer, pseudostereo and basewidth enlargement – simplified controlling of volume, bass, treble etc. – increased audio bandwidth for FM-Audio-signals (20 Hz – 15 kHz, ±1 dB)
