MSM5218 Description
The MSM5218 is a plete voice analysis/synthesis IC featuring the Adaptive Differential Pulse Code Modulation (ADPCM) method of data pression. The MSM5218 contains an analysis stage where serial PCM data is pressed to 3- or 4-bit parallel ADPCM data. In addition, a synthesis stage synthesizes PCM data from ADPCM data.
