I am reading about RFID systems and designs. And I stumbled upto this Digikey article - https://www.digikey.com.au/en/articles/a-designers-guide-to-rfid.
I am really confused with Figure 5 in that article.
In the above IC Diagram, I am really confused with Pin 2, Pin 4 Pin 14. How does these three pins work?
How is the transmission TX from pin 2 and pin 4 happening? And how is the information at pin 14 received?
Doesn't pin 14 receive whatever pin 2 sends? - I agree when some passive RF Antenna is bought nearby, RX plays a role. But I am not clear on how this IC functions in proper operating conditions.
Request you to explain how the pins 2, 4 and 14 work during RF Transmission and reception and how the values are selected.
