KEY ON
Tx OUT
When any one of the single-shot keys is depressed , the above single-shot signal is transmitted in 2 cycles, and
the transmitting output ends.

KEY ON
Tx OUT
When any one of the continuous keys is depressed, the above continuous signal is 2 cycles output, repeatedly
output 208a pause and 2 cycles is 2 pause of 208a.
6.5 CARRIER WAVE
About 50~100mA current is normally applied through an infrared LED in order to extend an infrared ray reaching
distance. Therefore, if a time, when LED is ON, is shortened as could as possible , it leads to reduction in power
consumption. On this IC, when single-shot or continuous signal is transmitting, each bit is switching by a carrier of
duty 1/3, output after the pulse modulated.
Carrier(fc) is decided by oscillation frequency fosc by means of XT and non-XT,
fc=fosc/12(Hz), fc=38kHz at fosc=455kHz.
