SC5260
310 ADDRESS REMOTE CONTROL ENCODER
DESCRIPTION
The SC5260 is a remote control encoder paired with either SC5260 or
SC5272 utilizing COMS Technology. It encodes data and address pins
into a serial coded waveform suitable for RF modulation. SC5260 has a
maximum of 10 bits tri-state address pins providing up to 59,049 (or 310)
address codes; thereby, drastically reducing any code collision and
unauthorized code scanning possibilities.
SC5260 is one of the first generation of Encoder/Decoder ICs. When
paired with SC5270, this encoder/decoder (SC5260/SC5270) pair can
operate at very wide temperature range (see Features). Thus, this very
important feature enables your Encoder/Decoder to operate under the
worst environmental condition.

Description
Code Address Pin Nos.0~7
These eight tri-state pins ate detected by SC5260 to determine the encoded
waveform bit0~bit7. Each bit can be set to “0”, “1”, or “f”(floating).
Code Address pin Nos.8~9/Data Pin Nos.3~2.
These two tri-state pins are detected by SC5260 to determine the encoded
waveform bit8~bit9. When these pins ate used as address pins (as in SC5260-
R2), they can be set to “0”, “1”, or “f”(floating). When these pins are used as data
pins (as in SC5260-R4), they can only be set to “0”or “1”.
Data Pin Nos. 1~0. These pins can only be set to “0”or “1”.
Oscillator Pin A resistor connected between the OSC Pin and the VCC
determines the fundamental frequency of the SC5260.
Data Output Pin. The encoded waveform is serially outputted to this pin. When
SC5260 is not transmitting, DOUT outputs low (VSS) voltage.

FUNCTIONAL DESCRIPTION
SC5260 encodes the code address and data set at A0~A7, A8/D3, A9/D2, D1 and D0 into a special waveform
and outputs it to the DOUT when any of the data pins is tied to high. This waveform is fed to the RF Modulator for
transmission. The transmitted radio frequency is received by the RF demodulator and reshaped into the special
waveform. SC5270 (or SC5272) is then used to decode the waveform and set the corresponding output pin(s).
Thus completing a remote control encoding and decoding function.
1. RF Operation
1) Code Bits
A Code Bits is the basic component of the encoded waveform, and can be classified as either an AD
(Address/Data) Bit or a SYNC (Synchronous) Bit.
Address/Data (AD) Bit Waveform
An AD Bit can be designated as Bit “0”, “1”, or “f”if it is in low, high or floating state respectively. One bit
waveform consists of 2 pulse cycles. Each pulse cycle has 512 oscillating clock periods. For further details,
please refer to the diagram below:
Where: α = Oscillating Clock Period
