Onboard MT8870 complex frequency decoding chip,onboard voice input interface,onboard 5 LED indicator, easy to view the output status.. It is a complete DTMF receiver integrating both the bandsplit filter and digital decoder functions.. After receiving the DTMF signal, it splits the signal into a high frequency band and a low frequency band, and sends the signal to the digital decoder to decode the key value, and then the solved key value is in a binary manner with four lines Q1, Q2, Q3, Q4 output to the external shared Bus.. When the MT8870 solves a button value and outputs it to the outside, its STD pin will rise from a low state to a high state, and then drop to a low state after a period of time. With this feature, when the signal is detected by this pin, , the value generated by the Q1-Q4 pin is immediately read into the CPU, and then the button value of the phone is solved.. The basic chip has been the main pin leads.PCB size 26.5 mm x24.5 mm.
