INTRODUCTION

S5G9802X01

16- DIP- 300A

TheS5G9802X01 is a CMOS integrated circuit for the infrared ray

remote control transmitter function to be used with the KS9801

for receiver. It can be applied to TV, VCR, VDP, CDP and AV

controller.

The S5G9802X01 has 18 functions, and a total of 75 commands can

be transmitted. These commands are generated by continuous

keys with multiple keying and 12 commands by single shot keys.

FUNCTIONAL DESCRIPTION

1. OSCILLATION CIRCUIT

•

The oscillation circuit is activated when any key is depressed. The ceramic resonator connected to X , X is

I O

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.

Since multiple keying is possible, key no. 1 - 6 are capable of outputting 63 commands through a combination

of D1 - D6 data.

Key No. 7 - h are the single shot keys for output 12 commands.

3. CUSTOM CODE (C1, C2, C3)

•

Custom code bit is made at one terminal with diodes connected through ST1 ~ ST3 strobe terminals

ST1 K6

(C3) (C2) (C1)

ST2

ST3

CCI

* Custom code bit consists

of 3 bits (C1,C2,C3),

and makes 8 custom codes.

CCI = Custom Code Input

Figure 4.

•

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.

Custom code bit

C1,C2 · · · · · · S5G9803X01 (24-DIP)

C2,C3 · · · · · · S5G9801X01 (16-DIP)

Note:

* Custom code bit “0” can not be used

* Custom code C1 can’t be used on the S5G9801X01 and

C3 can’t be used on the S5G9803X01

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.

•

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 X and X .
