| Semiconductor Semiconductor MSM5218 ADPCM Voice Analysis/Synthesis IC MSM5218 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 VDD BIN/TOC 12-bit S*R f SI SICK ADSI SCON XT XT S1 S2 VCK RESET T1 T2 VSS DAS 10 ADPCM Synthesizer 12 12-bit S*R SOCK 10-bit DAC DAOUT 12 ADPCM Analyzer 4B/3B ANA/SYN D3 D2 D1 D0 OSC Timing Circuit MSB/SO MSM5218 Semiconductor PIN CONFIGURATION (TOP VIEW) VCK 1 D0 2 D1 3 D2 4 D3 5 ANA/SYN 6 4B/3B 7 S1 8 S2 9 SICK 10 ADSI 11 VSS 12 24 V DD 23 XT 22 XT 21 RESET 20 BIN/TOC 19 MSB/SO 18 DAOUT 17 T2 16 T1 15 DAS 14 SOCK 13 SCON 24-Pin Plastic DIP Note: The product name actually printed on the product is "M5218".
