The MT8808AE is an integrated Subscriber Line Interface Circuit (SLIC) designed for analog telephone line interfaces. It provides all the necessary functions to interface a subscriber's telephone to a central office or private branch exchange (PBX). This includes battery feed, ring generation, supervision, and hybrid functions.

Applications:

• Analog Telephone Line Interfaces
• Central Office Equipment
• Private Branch Exchanges (PBXs)
• Voice over IP (VoIP) Gateways
• Customer Premises Equipment (CPE)

Features:

• Battery Feed
• Ring Generation
• Supervision
• Hybrid Function
• Over-Voltage Protection
• Loop Current Control

Benefits:

• Simplified Line Interface: Integrates all necessary functions into a single chip.
• Reduced Component Count: Minimizes external components and board space.
• Cost-Effective Solution: Provides a cost-optimized solution for analog telephone line interfaces.
• Reliable Operation: Over-voltage protection ensures robust performance in harsh environments.

Additional Details:

The MT8808AE provides battery feed to power the subscriber's telephone, ring generation to signal incoming calls, and supervision functions to monitor the line status. The hybrid function converts the two-wire telephone line signal to a four-wire signal for transmission and reception. Over-voltage protection protects the SLIC from voltage surges and transients. Loop current control optimizes the loop current for different line lengths. Specific technical characteristics include the battery feed voltage, the ring voltage, and the loop current range. Package type is typically DIP or SOIC.
