MX93032 - APPLICATION NOTE [M1 VERSION]

Description

MX93032-M1 is an engine chip on which digital answering machine (DAM) with full duplex speaker phone is implemented.

Besides, CAS tone detection capability and FSK decoder for Caller-ID service has also been implemented as well.

It provides speech processing / management modules

Features

  • Switchable 4.8kbps/12.8kbps speech compression/ decompression algorithm for message recording/playback.
  • Minimum 15 or 40 minutes of recording time for one 16M bits MX29F16A FLASH based on 12.8K or 4.8K compression rate, respectively.
  • Low (4.8kbps) or High (12.8kbps) compression rate with silence management technique for voice prompt making. Voice prompt can be stored in Flash memory.
  • Support total 127 messages, maximum 7 OGMs and maximum 8 personal mailbox.

MX93032 APPLICATION NOTE [M1 VERSION] 1.0 GENERAL DESCRIPTIONS • MX93032-M1 is an engine chip on which digital answering machine (DAM) with full duplex speaker phone is implemented. Besides, CAS tone detection capability and FSK decoder for Caller-ID service has also been implemented as well. • It provides speech processing / management modules, including speech compression/decompression, silence management, telephone line signal processing, Macronix MX29F16A FLASH management, line echo cancellation and acoustical echo cancellation, etc. • The MX93032-M1 has built-in DSP mode and MCU mode. In DSP mode, users do not need external microprocessors and can effectively reduce the overall system cost in DAM with full-duplex speakerphone system.
