5. Oscillation Circuit
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.
6. CODE FORMAT MODES
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
Code, 8 bits Custom Code followed by a sync. bit, Separator and 8 bits Data Code followed by another sync. bit.
Please refer to the diagram below.
SC50560 Version
The oscillation circuit may be constructed by connected a
SC50560 code format comes in three modes: 001, 002 and 003. Please refer to the diagram below:
Both SC50560-001 and SC50560-002 make use of the same operation when the input from terminal CS and
