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

鈥?ADPCM data compatible with OKI's synthesis IC MSM5205

鈥?Analysis/synthesis switching pin provided

鈥?Lower power consumption achieved by one-chip CMOS IC

鈥?Built-in 10-bit D/A converter for analog output

鈥?Variable sampling frequency (4 kHz, 6 kHz, 8 kHz)

鈥?Master clock frequency: 384 kHz

鈥?Package: 24-pin plastic DIP (DIP24-P-600) (Product name: MSM5218RS)
