The MT8870DS by Zarlink Semiconductor is a comprehensive Dual-Tone Multi-Frequency (DTMF) receiver. It integrates both the bandsplit filter and digital decoder functionalities, utilizing switched capacitor techniques for high and low group filters. The digital decoder employs counting techniques to detect and decode all 16 DTMF tone-pairs into a 4-bit code.
Key features include low power consumption, an internal gain setting amplifier, and adjustable guard time, providing central office quality. The device also supports power-down and inhibit modes. It is backward compatible with MT8870C and MT8870C-1.
This DTMF receiver is suitable for various applications such as receiver systems for British Telecom (BT) or CEPT Spec, paging systems, repeater systems, mobile radio, credit card systems, remote control, personal computers, and telephone answering machines. The MT8870DS is available in an 18-SOIC package and operates within a temperature range of -40°C to +85°C.
External component count is minimized due to on-chip provision of a differential input amplifier, clock oscillator, and a latched three-state bus interface.
