• Carrier frequency: 13.56 MHz ± 7kHz
• ASK modulation 100%
and 10%
Two types of coding are supported by the transpondersfully compliant with ISO 15693:
1 out of 256: one byte is coded at a time
Example: coding 197 = <C5> = 11000101
time
ISO/IEC 15693Coding the information
1 out of 4: two bits are coded at a time
Example: coding 197 = <C5> = 11000101

ISO/IEC 15693Start Of Frame (SOF) - End Of Frame (EOF)
Start of frame sequence to selectthe « 1 out of 256 » coding mode
Start of frame sequence to selectthe « 1 out of 4 » coding mode
End of frame sequencefor both coding modes
• Load modulation amplitude: minimum 10 mV
