FUNCTIONAL DESCRIPTION
1. OSCILLATION CIRCUIT
• The oscillation circuit is activated when any key is depressed. The ceramic resonator connected to XI, XO is
normally operated at 455kHz oscillation frequency.

2. KEY INPUT & STROBE OUTPUT
• All key input pins have a pull down resistor to VSS. 18 keys can be connected by key input K1 - K6 and 6x3
matrix by means of strobe signal ST1 - ST3.
• Multiple keying is possible for the keys connected to ST1 Line (key No. 1 - 6), and all depressed keys are
output (Output becomes continuous pulses).
• Among the strobe signal lines, priority is set in the order, ST1>ST2>ST3.
The keys connected to ST2 and ST3 lines have priority and when input is made through more than 2 keys, and
single signal is preferentially output in order of K1 - K6.
• Finally, the keys connected to ST2 and ST3 lines are for single signals and no second signal is transmitted
unless input is made again after the key is released once.

* Custom code bit consists
of 3 bits (C1,C2,C3),
and makes 8 custom codes.
• Custom code bit becomes 1 when diodes are connected to the CCI terminal through strobe signal (ST1 - ST3),
but if diodes are not connected, custom code bit becomes “0”. (In the above diagram, C1. C2 and C3 are “1”, 1
and data.)
• Custom code bit of the S5G9802X01 has 3 bits. However, the S5G9801X01 (16-DIP) which is a receiver, and
the S5G9803X01 (24-DIP) are able to use only C2, C3, and C1, C2 custom code bits, respectively.
• For C1 and C3 custom code bit data not used on the S5G9801X01 and S5G9803X01, you must transmit “1”,
and diodes must be connected as follows.

• Basic remote waveform is 12-bit serial data in configuration as shown above.
• The time of each bit T is decided as shown below by the oscillation frequency fOSC, by means of 01 and 00.
• T = (1/fOSC) X 192[sec]

• When single shot or continous signal is transmitting, each code bit is switched by a carrier of duty 1/3 output
after the pulse modulated.
• In 455kHz oscillation the signal is modulated by 1/3 duty 38MHz, and carrier (fC) is decided by oscillation
frequency fOSC by means of XI and XO.
