Other Parts Discussed in Thread: TRF7960

Hi

According to standard ISO/IEC 15693 data rates are defined as follows

1 out of 4 pulse position modulation 2 bits are coded as the position of a 9.44 µs pause in a 75.52 µs symbol time, giving a bit rate of 26.48 kilobits per second The least-significant bits are sent first.

1 out of 256 pulse position modulation 8 bits are coded as the position of a 9.44 µs pause in a 4.833 ms symbol time, giving a bit rate of 1.65 kbit/s.

But TRF7960 allows both data rate configuration for both modes. Please clarify on this and how does these configuration affect read range and read sensitivity of RFID board.

Awaiting your response

Thank you
