1 / 8 page MC14497 MOTOROLA 1 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 compatible with the MC14497. Typically, the decoding resides in MCU software. • Both FSK/AM Modulation Selectable • 62 Channels (Up to 62 Keys) • Reference Oscillator Controlled by Inexpensive Ceramic Resonator: Maximum Frequency = 500 kHz • Very Low Duty Cycle • Very Low Standby Current: 50 µA Maximum • Infrared Transmission • Selectable Start–Bit Polarity (AM Only) • Shifted Key Mode Available • Wide Operating Voltage Range: 4 to 10 V • See Application Notes AN1016 and AN1203 BLOCK DIAGRAM 17 E1 2 E2 1 E3 16 E4 15 E5 14 E6 10 E7 11 E8 ENCODER 7–BIT SR SEQUENCE CONTROL 3–BIT LATCH OUTPUT CONTROL DIVIDER ÷ 10/12 MUX SCANNER DIVIDER ÷ 32 DIVIDER ÷ 16 OSC STANDBY 7 6 5 4 FK3 E9 3 FK1 A4 A3 A2 A1 9 VDD 18 8 IN OUT 12 13 500 kHz CERAMIC RESONATOR KEYBOARD Order this document by MC14497/D MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14497 P SUFFIX PLASTIC DIP CASE 707 ORDERING INFORMATION MC14497P Plastic DIP PIN ASSIGNMENT A3 E9 E2 E3 VSS SIGNAL OUT A1 A2 A4 E5 E4 E1 VDD E7 E8 OSCin OSCout E6 14 15 16 17 18 10 11 12 13 5 4 3 2 1 9 8 7 6 18 1 © Motorola, Inc. 1995 SAME AS IN DL136/D R3 |
