Princeton TechnologyCorp.Remote Control Encoder PT2262Tel : 886-2-29162151Fax : 886-2-29174598URL: http://www.princeton.com.twThe Code Bits A0 ~ A5 and A6/D5 ~ A11/D0 are determined by the states of A0 ~ A5 and A6/D5 ~ 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.

The built–in oscillator circuitry of PT2262 allows a precision oscillator to be constructed by connecting an external resistor between OSC1 and OSC2pins. For PT2272 to decode correctly the received waveform, the

oscillator frequency of PT2272 must be 2.5 ~ 8 times that of transmitting PT2262. The typical oscillator frequency with various resistor values for both PT2262 and PT2272 are shown below :

PT2262 4.7 MΩ 3.3 MΩ 1.2 MΩ PT2272 820 KΩ* 680 KΩ* 200 KΩ**

Note: * -- Operates when PT2272 's Vcc=5V to 15V

** -- Operates when PT2272's Vcc=3V to 15V

This means that if PT2272 supply voltage is lower than 5 Volts, you need to use alower oscillator resistor value for both PT2262 and PT2272.

except for the output waveform that has a carrier frequency of 38 KHz. Details areas follows:

The Code Bits are further modulated with a 38 KHz carrier frequency and can be “0” , “1” or “f” bit. Their waveforms are shown in the diagram below. Note : λ = 2 clock lengths

Likewise, a Code Frame is made up of Code Words and the format is the same as that of RF Type of Operation.
