(OSI Model Layer 3 and below)
• Separate internal high-PSRR power supplies
for analog, digital, and PA sections provides
noise isolation for superior read range and
reliability
• Dual receiver input with AM and PM
demodulation to minimize communication
holes (patent pending).
• Receiver AM and PM RSSI
• Reader-to-reader anti-collision
• High Integration reduces total BOM and
board area

DESCRIPTION
The TRF7960/61 is an integrated analog front end &
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.
