The TRF7960/61 is an integrated analog front end
11 User-Programmable Registers
and data framing system for a 13.56-MHz RFID
reader system. Built-in programming options make it
Selectable Receiver Gain and AGC
suitable for a wide range of applications both in
Programmable Output Power
proximity and vicinity RFID systems.
(100 mW or 200 mW)
The reader is configured by selecting the desired
Adjustable ASK Modulation Range
protocol in the control registers. Direct access to all
(8% to 30%)
control registers allows fine tuning of various reader
Built-In Receiver Band-Pass Filter With
parameters as needed.
User-Selectable Corner Frequencies
• Wide Operating Voltage Range of 2.7 V to
5.5 V
