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. PT2294 is then used to decode the waveform and set the corresponding output pin(s). Thus completing a remote control encoding and decoding function. RF OPERATION CODE BITS A Code Bit 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 16 oscillating time periods. For further details, please refer to the diagram below: α OSC 1 bi t = 32α B IT 0 4α B IT 1 12 α 4α BIT f F l oati ng where: α=Oscillating Clock Period Synchronous (Sync.) Bit Waveform The Synchronous Bit Waveform is 4-bit long with 1/8 bit width pulse.

A Code Word consists of 12 AD bits followed by one Sync Bit. The 12 AD bits are determined by the corresponding states of A0 ~ A7 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 Data Type where the address has eight (8) bits, the transmitting format is: 8 Address Bits 4 Data Bits Sync. bit PT2264/PT2294 have a maximum of twelve (12) Address Bits, four (4) Address/Data bits. The following diagram shows the code bits with their corresponding pins. A0 First bit transmitted ↓ A2 A3 A4 A5 A6 A1 A7 A8/D3 A9/D2 A10/D1 A11/D0 SYNC BIT One Complete Code Word 0 1 2 3 4 Data Data Data Data Data A0 A0 A0 A0 A0 A1 A1 A1 A1 A1 A2 A2 A2 A2 A2 A3 A3 A3 A3 A3 A4 A4 A4 A4 A4 A5 A5 A5 A5 A5 A6 A6 A6 A6 A6 A7 A7 A7 A7 A7 A8 A8 A8 A8 D3 A9 A9 A9 D2 D2 A10 A10 D1 D1 D1 A11 D0 D0 D0 D0 Sync Bit Sync Bit Sync Bit Sync Bit Sync Bit The Code Bits A0 ~ A7 and A8/D3 ~ A11/D0 are determined by the states of A0 ~ A7 and A8/D3 ~ A11/D0 pins. For example, when the A0 (Pin No. 1) is set to “1” (VCC), the Code Bit A0 is synthesized as “1” bit. In the same manner, when it (A0 Pin) is set to “0” (VSS) or left floating, the Code Bit A0 is synthesized as a “0” or “f” bit respectively.

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. /TE DOUT one frame (=4 word) one frame one frame SIGNAL RESISTOR OSCILLATOR The built–in oscillator circuitry of PT2264 allows a precision oscillator to be constructed by connecting an external resistor between OSC1 and OSC2 pins. For PT2294 to decode correctly the received waveform, the oscillator frequency of PT2294 must be 2.5 ~ 8 times that of transmitting PT2264.
