5. Osc illa tion Circ uit

The oscillation circuit may be constructed by connected a

ceramic resonator between the OSCI and OSCO. Please

refer to the diagram right. When the references signal is set

to 455KHz the carrier can be set at 38KHz. When no key

input is pressed, the oscillation circuit is normally stopped,

thereby, lower power dissipation.

Both SC50560-001 and SC50560-002 make use of the same operation when the input from terminal CS and

the scan output (KO0 to KO4) are connected to make the custom code selection with the exception of the number

of word transmitted. Please refer to the table above:

MODE A

The diagram below gives us the transmission code format for Mode A. One Code Word consists of the Leader

Code, 8 bits Custom Code followed by a sync. bit, Separator and 8 bits Data Code followed by another sync. bit.
