MT8870DS Description

Short technical summary and product information.

The MT8870DS from Zarlink Semiconductor is a comprehensive DTMF (Dual-Tone Multi-Frequency) receiver designed for various applications. It integrates both the bandsplit filter and digital decoder functions, utilizing switched capacitor techniques for high and low group filters, and digital counting for tone detection and decoding.

 

Key features include low power consumption, an internal gain setting amplifier, adjustable guard time, and central office quality performance. The device also supports power-down and inhibit modes for enhanced control. It is backward compatible with MT8870C and MT8870C-1.

 

This DTMF receiver is suitable for applications such as receiver systems for British Telecom or CEPT specifications, paging systems, repeater systems, mobile radio, credit card systems, remote control, personal computers, and telephone answering machines. The MT8870DS is available in an 18-pin SOIC package suitable for surface mounting.

 

It operates within a temperature range of -40°C to +85°C.
