ic sm6136b
hey!....this is jack..
i can give the information about this chip....don't worry...
the sm6136B is an encoder chip commonly found in toy remote cars...
these encoders transmit the data to the reciever.....by using frequency matching
technique the main thing about this encoder chip is that each time when you press a key it encoder the four bit code....just like this...
for example you have the four keys...1,2,3,4
if you press the key 2 it encodes the data like this...
0010
pressing key1
0001
pressing key 3
0011
pressing key 4
0100
this encoded data is transmitted using a transmitter
at first this encoded data is modulated and it is synchronized by the clock pulses..
and transmitted through the antenna....
whenever this transmitted data is recived at the recieving end the modulated wave is passed through a demodulator(this process is called demodulation...which is the reverse process of modulation...)and this modulated wave which is arrived at the
receiver is demodulated by passing the modulated wave and the synchronized clock pulses (which have the same frequency matches with transmitter frequency) through the demodulator and the output of the demodulator is fed to the decoder
chip it receives the data serially and decodes the data parallelly...
i have sent the pin diagram of sm6136b transmitter and the sm6135b reciver chips// you should see this....
