Description
Electronic Component Model: MX93011BFC is an engine chip that implements a digital answering machine (DAM) with a full duplex speakerphone. It also has CAS tone detection capability and FSK decoder for Caller-ID service. The chip provides speech processing/management modules such as speech compression/decompression, silence management, telephone line signal processing, FLASH memory management, line echo cancellation, and acoustical echo cancellation, among others. It can operate in DSP mode or MCU mode, with the former eliminating the need for external microprocessors and reducing overall system cost in DAM with full-duplex speakerphone 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 a total of 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 DSP mode and MCU mode
- Standard sample program written by 8051 assembly 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 MX93011BFC engine chip is commonly used in digital answering machines with full duplex speakerphone systems. It is also suitable for applications that require CAS tone detection, FSK decoding for Caller-ID services, and speech processing/management capabilities.
