M3325
Decoder
MPEG-1, MPEG-2 MP@ML video decoding Bulit-in System Control Integrated MPEG-2, Dobly Digital, audio/video decodes Suports different channel Interfaces such CD/DVD, ATAPI
ALI's M3325 Audio Video Decoder Single Chip another advanced from that provides decoding consumer electronics. M3325 support MPEG2 MP@ML JPEG decoding offers fast-forward, stop, freeze, frame-by-frame, slow motion backward properties. audio properties real time decoding MPEG layer I/II Audio, Dolby Digital, decoding. M3325 supports PCM, Dolby Digital bitstream bitstream output 958. audio post-processing M3325 supports Karaoke function, stereo enhancement, Cinema Effect Virtual Surround downmixed multi-channel audio source while using 2-speaker environment. further reduce system cost, M3325 provides built-in MCU, Progressive Scan processor, encoder Audio ADC. Furthermore, uses single external clock. This chip packed 208-pin PQFP using 2.5V CMOS technology.
