Description
Electronic Component Model: MX93011AFC is an engine chip that combines a digital answering machine (DAM) with a full duplex speaker phone. It also includes CAS tone detection capability and FSK decoder for Caller-ID service. The chip provides speech processing and management modules, including speech compression/decompression, silence management, telephone line signal processing, Macronix MX29F16A FLASH management, line echo cancellation, and acoustical echo cancellation. It can be operated in either DSP mode or MCU mode. In DSP mode, it eliminates the need for external microprocessors, reducing the system cost in DAM with full-duplex speakerphone system. In MCU mode, it can be controlled by an MCU (micro controller) via a 8 bit parallel or serial interface.
Specifications and 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 mailboxes.
• DTMF generation and detection with near-end echo cancellation.
• Provide single low crystal solution (FLL).
• Built-in DSP mode and MCU mode. In DSP mode, user can mask the system code into the MX93032-M1. In MCU mode, user can control the MX93032-M1 via MCU (microcontroller).
• Provide standard sample program written by 8051 assemble for customer development.
• Full duplex speakerphone with both acoustical echo canceller (AEC) and line echo canceller (LEC).
• Built-in CAS signal detector for monitoring the presence CPE alerting signal in Calling Identity Delivery on Call Waiting.
• FSK decoder for Calling Identity Delivery on CID Type I and CID Type II.
• Caller ID Type II can be turned on under speakerphone mode.
• Auto detecting MCU mode and DSP mode.Application Scenarios
The MX93011AFC engine chip can be used in various applications including digital answering machines with full-duplex speakerphone systems, Caller-ID services, voice prompt systems, and other systems that require speech processing and management.
