Remote Control Encoder
PT2260
PT2260 remote control encoder paired with either PT2270 PT2272 utilizing CMOS Technology. encodes data address pins into serial coded waveform suitable modulation. PT2260 maximum bits tri-state address pins providing 59,049 310) address codes; thereby, drastically reducing code collision unauthorized code scanning possibilities. PT2260 first generation Encoder/Decoder that utilizes unique Technology. When paired with PT2270, this encoder/decoder (PT2260/PT2270) pair operate very wide temperature range (see Features). Thus, this very important feature enables your Encoder/Decoder operate under worst environmental condition.

Name Description Code Address Nos. These eight tri-state pins detected PT2260 determine encoded waveform Each "0", "1", (floating). Code Address 9/Data These tri-state pins detected PT2260 determine encoded waveform When these pins used address pins PT2260-R2), they "0", "1", (floating). When these pins used data pins PT2260-R4), they only "1". Data 1/0. These pins only Oscillator resistor connected between determines fundamental frequency PT2260 Data Output Pin. encoded waveform serially outputted this pin.

FUNCTION PT2260 encodes code address data A8/D3, A9/D2, into special waveform outputs DOUT when data pins tied high. This waveform modulator transmission. transmitted radio frequency received demodulator reshaped into special waveform. PT2270 PT2272) then used decode waveform corresponding output pin(s). Thus completing remote control encoding decoding function.
