The Synchronous bit waveform is 4 bits long with 1/8 bit width pulse. Please refer to the diagram below:
1/8 bit width=4a
4 bit width=128a
Note: 1bit =32a
Code word
A group of Code Bits is called a Code Word. A Code Word consists of 12 AD bits followed by one Sync. Bit. The
12 AD bits are interpreted as either address or data bits depending on the SC5272 version used. Please refer to

SYNC
Single Resistor Oscillator
The Build-in oscillator circuitry of SC5272 allows a precision oscillator to be constructed by connecting an
external resistor between OSC1 and OSC2 pins. For SC5272 to decode correctly the received waveform, the
oscillator frequency of SC5272 must be 2.5 ~8 times that of transmitting SC5262. It is a good practice to center the
SC5272 oscillator frequency in the window to gain best window margin at both sides. The typical oscillator
frequency with various resistor values for both SC5262 and SC5272 are shown below:
