Overview

  • Close loop adjustment of ASK modulation for accurate control of modulation depth in case of ISO-14443B protocol
  • Low power (3.5 μA) NFC target mode
  • AM/PM demodulator
  • Accurate RF envelope measurement (8-bit A/D converter)
  • High output power at 3.3 V power supply: - Up to 700 mW in case regulator is externally shorted - Up to 500 mW in case of differential output when antenna trimming is used - Up to 125 mW in case of single ended output when antenna trimming is used
  • Squelch for gain reduction, to compensate for noise generated by tag processing
  • Automatic Antenna tuning (AAT)
  • Transparent mode
  • Amplitude and phase measurement
  • Supporting 13.56 MHz and 27.12 MHz quartz oscillator with fast start-up
