Remote Control Encoder IC
DESCRIPTION
PT2264 is a remote control encoder paired with PT2294 utilizing CMOS Technology. It encodes data
and address pins into a serial coded waveform suitable for RF modulation. PT2264 has a maximum of
12 bits of tri-state address pins providing up to 531,441 (or 3
reducing any code collision and unauthorized code scanning possibilities.

... I determine the encoded waveform bit 0 ~ bit 9. Each pin can be set to “0”, “1” or “f” (floating ). Code Address Pin Nos.8 ~ 11/Data Pin Nos These four tri-state pins are detected by PT2264 to determine the encoded waveform bit10, bit11. A8/ When these pins are used as address pins, they A11/D0 can be set to “ ...

... Remote Control Encoder IC FUNCTIONAL DESCRIPTION PT2264 encodes the code address and data set and A8/D3 ~ A11/D0 into a special waveform and outputs it to the DOUT when /TE is pulled to “0” (Low State). This waveform is fed to either the RF modulator for transmission. The transmitted radio frequency is received by the RF demodulator receiver and reshaped to the special waveform ...

... A group of Code Bits is called a Code Word. A Code Word consists bits followed by one Sync Bit. The 12 AD bits are determined by the corresponding states and A8/D3 ~ A11/D0 pins at the time of transmission. When Data Type of PT2264 is used, the address bits will decrease accordingly. For example: In the 4 Datas Type where the address has eight (8) bits, the transmitting format is: 8 Address Bits PT2264 / PT2294 have a maximum of twelve (12) Address Bits, four (4) Address/Data bits ...

... Remote Control Encoder IC CODE FRAME A Code Frame consists of four (4) continuous Code Words. When PT2264 detects “0” on the /TE (meaning, the /TE is active “low”), it outputs a Code Frame at DOUT. If /TE is still active at the time the Code Frame transmission ends, PT2264 outputs another Code Frame. It should be noted that the Code Frame is synthesized at the time of transmission ...
