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.

MSM5218 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)
