MT8870 DTMF Speech Decoding Module

This component is ideally suited to adding dual tone multi-frequency (DTMF) decoding to your project. This detection module interprets the incoming tone and produces a coded output that can be connected to all manner of microcontrollers. DTMF is commonly found in touch tone devices such as a phone. The tone is a combination of two separate sine waves that produce a unique signal that can be transmitted or heard. When the module receives the signal it is able to decode it and produce a binary output that can be used in other devices. The module shows the state of the signal through onboard LEDs. The MT8870 Tone Decoder is a kind of commonly used multi-frequency decode IC product developed by the MITEL company. It is a complete DTMF receiver. After it received the DTMF signal, it will divide the signal into high-frequency group and low-frequency group and send the signal to the digital decoder which can figure out the key value then send it to the outside Bus via four lines( Q1, Q2, Q3, Q4) as the binary form.

DTMF Decoder Module decode DTMF audio signal to 4 bit binary TTL level output with LED indication. Suitable for use with microcontroller applications. Main Features: Decodes DTMF as 4 bit binaryTTL level output for direct connection to microcontrollersLow power 5V DC operationLED indication of outputsSimple to useBased on excellent HT9170B IC Applications: Remote Control systemsCaller ID applicationsFM receiver based remote controlRemote control using Mobile phone Specification: Operating Voltage 5 V DC Regulated power supply inputOperating Current 100 mA Information: Connect regulated +5V DC supply for operation of the board. Outputs Q1-4 and VT are active high output at 5V level. If any LED is on means that output is at the high level. VT LED blinks once a new DTMF tone is received. The binary data appears at Q1 to Q4. A detail of this output is on next page. The input signal can be from an audio source like microphone amplifier, FM radio receiver, wired phone line. Please note when connecting landline phone signal, do not connect ground wire of board to phone line directly. Use a 100nF capacitor in series to phone line wires at ground.
