MSM5218中文资料ADPCM Voice Analysis/Synthesis IC数据手册OKI规格书

描述 Description

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 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)
• Master clock frequency: 384 kHz
• Package: 24-pin plastic DIP (DIP24-P-600) (Product name: MSM5218RS)
