MSM7732
Audio CODEC
GENERAL DESCRIPTION
The MSM7732 is a single-channel full duplex CODEC LSI device which performs mutual
transcoding between analog voice band signals ranging from 300 to 3400 Hz and the 64 kbps
PCM serial data.
Provided with such functions as DTMF Tone generation, transmit/receive data gain control,
and side-tone path, the MSM7732 is best suited for telephone terminals in digital wireless
systems.
FEATURES
• Single 3 V power supply
• Coding format: PCM m-law/PCM A-law/14-bit linear mode selectable
• PCM interface timing: Long frame synchronous timing/short frame synchronous timing
• Transmit/receive full-duplex operation
• Serial PCM transmission data rate: 64 kbps to 2048 kbps
• Low power consumption
• Analog output stage:
• Transmit/receive mute, transmit/receive programmable gain control
• Side tone path
• Built-in DTMF tone generator
• Transmit slope filter selectable
• Serial MCU interface control
• Package:
