PCM Remote Control Transmitter
The MC14497 is a PCM remote control transmitter realized in CMOS technology. Using a dual- single (FSK/AM) frequency bi- phase modulation, the transmitter is designed to work with the MC3373 receiver. Information on the MC3373 can be found in the Motorola Linear and Interface Integrated Circuits book (DL128/D).
There is not a decoder device which is patible with the MC14497. Typically, the decoding resides in MCU software.
