¡ Semiconductor MSM5218 ¡ Semiconductor MSM5218 ADPCM Voice Analysis/Synthesis IC GENERAL DESCRIPTION The MSM5218 is a complete voice analysis/synthesis IC featuring the Adaptive Differential Pulse Code Modulation (ADPCM) method of data compression. The MSM5218 contains an analysis stage where serial PCM data is compressed to 3- or 4-bit parallel ADPCM data. In addition, a synthesis stage synthesizes PCM data from ADPCM data.

FEATURES

  • ADPCM data compatible with OKI's synthesis IC MSM5205
  • Analysis/synthesis switching pin provided
  • Lower power consumption achieved by one-chip CMOS IC
  • Built-in 10-bit D/A converter for analog output
  • Variable sampling frequency (4 kHz, 6 kHz, 8 kHz)
  • Master clock frequency: 384 kHz
  • Package: 24-pin plastic DIP (DIP24-P-600) (Product name: MSM5218RS) BLOCK DIAGRAM BIN/TOC SICK ADSI SCON XT XT VCK RESET 4B/3B ANA/SYN DAOUT MSB/SO SOCK 12-bit S•R f SI OSC Timing Circuit VDD ADPCM Analyzer ADPCM Synthesizer 10-bit DAC 12-bit S•R DAS VSS
