DESCRIPTION
The TRF7960/61 is an integrated analog front end
and data framing system for a 13.56-MHz RFID
reader system. Built-in programming options make it
suitable for a wide range of applications both in
proximity and vicinity RFID systems.
The reader is configured by selecting the desired
protocol in the control registers. Direct access to all
control registers allows fine tuning of various reader
parameters as needed.
