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:

Sync. Bit
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:
