OPERATING PRINCIPLES

1. POR (Power On Reset) CIRCUIT

To initialize the internal state at time of power ON, it is necessary to perform the initialization.
The initialization is carried out when a capacitor is connected to the code bit terminal.

In the case of S5G9803, connect a capacitor to CODE2 and CODE3.

2. OSCILLATION CIRCUIT

The RC oscillation circuit is normally operated at 38kHz oscillation frequency.
(The RC is connected between OSC terminal and VSS.)

3. RECEIVING SIGNAL INPUT CIRCUIT

Signal received by the light receiving element is sent through the Pre-Amp to the detector, when a 38 kHz carrier
wave is eliminated and the signal enters a REMIN PIN of the receiving signal input circuit. The receiving signal
input circuit (REMIN) has a built-in Schmitt trigger for shaping receiving signal waveforms to eliminate rounding.

4. RECEIVING SIGNAL CHECK

The receiving signal check is to check the 2-cycle transmitting signal sent from the transmitter to check whether it is
a normal signal or not.

12 Bits

First Data

12 Bits

Second Data

Figure 6.

The first data is stored in the 12-bit data register. Then, when the second data is entered, the previous data is
pushed out from the data register one by one.
The pushed out data and incoming data are checked to see if they are same.
If any errors are caused during the 12-bit receiving data check, the system is reset at that time. And when all receiv­ing data are same, output is raised from L level to H level.

The status of receiving data, register clock and check pulse are shown below.
Register clock is provided in the data center by taking frequency margins of the transmitter and the receiver into
consideration.

5. CODE BIT COMPARISON

In order to prevent interference with other machines and apparatuses, C1, C2 and C3 code bits are provided for
checking whether or not the transmitter codes agree to the receiver codes.
Only when both codes agree, the internal latch pulse is generated to latch receiving data, and output is raised from
“L” level to “H” level.
If both codes do not agree, latch pulse is not generated and output remains at “L” level.
Code bits used differ depending on receiver as shown below:

6. EXPLANATION OF OUTPUT PULSE SP, CP, TP

1) SP1 - SP10 (Single Pulse)
When a single key is depressed, after checking the 12-bit receiving data, if the data agree, a single pulse is output.
The output is raised from “L” level to “H” level and returned again to “L” level after about 107 msec.

About 107 msec

2) CP1 - CP6 (Continuous Pulse)
Continuous pulse is output by the first latch pulse after key ON. Output is kept at “H” level as a long as a continuous
signal is input.
When the key is released and continuous signal is stopped about 160 msec later, output is reversed to “L” level by
the last latch pulse.
Further, CP1 - CP6 are able to output simultaneously in parallel method, maximum sextet outputs at “H” level by
continuous signals sent from the transmitter.
These outputs are optimum as outputs of REC-PLAY, REC-PAUSE and CUE/REVIEW of a tape deck.

Figure 11.

The combination of code bits of S5G9802X01 and S5G9801X01 is shown in Table 1.
To make the code bit to 1 on S5G9802X01, connect diodes to the CCI terminal from ST1 - ST3 terminals. To set
Code Bit at 0, open the circuit.
S5G9801X01 has CODE2 and CODE3 code terminals. Code bit of C1 has been pulled up in IC and C1 is always
kept at 1 status.
Therefore, on transmitter S5G9802X01, it is necessary to keep C1 code bit at 1.

Therefore, on transmitter S5G9802X01 it is necessary to keep code bit C3 at 1.
To keep code bit C3 at 1, connect a diode to the Cci terminal from ST3 terminal.

3. If input voltage above VDD +0.3 V may be applied to the REMIN Input Terminal (2 PIN), connect about ten resis­tors in series to the REMIN Input Terminal. (This is to prevent latch-up).
