Description
Electronic Component Model: MX93L111FCG is an engine chip designed for digital answering machines (DAM) with a full duplex speakerphone. It is also equipped with CAS tone detection and FSK decoder for Caller-ID service. This chip provides various speech processing and management modules, including speech compression/decompression, silence management, telephone line signal processing, FLASH memory management, line echo cancellation, and acoustical echo cancellation. It can operate in both DSP mode and MCU mode, offering flexibility and cost-effectiveness in DAM systems.
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
- Support for total 127 messages, maximum 7 OGMs, and maximum 8 personal mailboxes
- DTMF generation and detection with near-end echo cancellation
- Single low crystal solution (FLL)
- Built-in 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 of 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 MX93L111FCG chip is primarily used in digital answering machines with full duplex speakerphone systems. It can also be used in devices that require speech processing and management, such as voice recorders or voice prompt systems. The chip's ability to handle Caller-ID services and echo cancellation makes it suitable for telecommunication applications as well.
