FUNCTIONAL DESCRIPTION

SC50560 is capable of transmitting up to 256 different instructions and 8 bits custom codes using a 16-bit PCM

Code with a leader code. Furthermore, oscillation is normally stopped when there is no operating, thereby, lower

power dissipation.

1. TRANSMISSION CODE

SC50560 transmission code consists of a leader code, 8 bits custom code (C0 to C7) followed by a sync. bit

and 8 bits data code (D0 to D7) followed another sync. bit. The custom and the data codes are separated by a

separator. Please refer to the diagram below:

One transmission Code Word consists of a 19-bit pulse (that is the leader pulse plus the 16 bits code) and the

separator. It is transferred in a 63.4ms for as long as the key is depressed. Please refer to the diagram below:
