MSM5218 - ADPCM Voice Analysis/Synthesis IC
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 synthesize
