ST3617 - Infrared remote control decoder

Key Features

of Protocol.
5 bit address and 6 bit command length.
Bi-phase coding (aka Manchester coding).
Carrier frequency of 36kHz or 38kHz.
Constant bit time of 1.778ms (64 cycles of 36 kHz), Different timing for 38Khz, Should be adjusted in decoder part by monitoring first two bits.
Manufacturer Philips Modulation RC5 Modulation The protocol uses bi-phase modulation (or so-called Manchester coding) of a 36kHz IR carrier frequency. All bits are of equal le.

There are two ways of getting data from chip, Data of 9600 baud rate or Serial Shift of data through RDY, CLK and DAT pins. Many remote control applications can be developed using the decoder. Block Diagram ST3617 needs only one component to work that is IR receiver like TSOP1738 or similar. The data is output as simple 2 bytes of serial data consisting of 16 bits of information for each key press on the remote.
