MSM5218中文资料冲电线数据手册PDF规格书

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 OKIs 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)
