DESCRIPTION

– Auto-configured default modes for each

supported ISO protocol

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.

– 11 user-programmable registers

– Selectable receiver gain and AGC

– Programmable output power

(100 mW or 200 mW)

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.

– Adjustable ASK Modulation Range

(8% to 30%)

– Built in receiver bandpass filter with user

selectable corner frequencies

•

Wide operating voltage range of 2.7 to 5.5 V

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Figure 1. Typical Application

A parallel or serial interface can be used for

communication between the MCU & reader. When

hardware encoders and decoders are used

(accelerators for different standards), transmission

and receive functions use a 12-byte FIFO register.

For direct transmit or receive functions, the

encoders/decoders can be bypassed in order for the

MCU to process the data in real time. The transmitter

has selectable output-power levels of 100 mW

(+20 dBm) or 200 mW (+23 dBm) into a 50 Ω load

(at 5 V supply) and is capable of ASK or OOK

modulation. Integrated voltage regulators ensure

power-supply noise rejection for the complete reader

system.

The receiver system also includes a framing system.

This system performs the CRC and/or parity check,

removes the EOF and SOF settings, and organizes

the data in bytes. Framed data is then accessible to

the MCU via a 12-byte FIFO register and MCU

interface. The framing supports ISO14443 and

ISO15693 protocols.

The TRF7960/61 supports data communication

levels between 1.8-5.5 V for MCU I/O interface while

also providing a data synchronization clock. An

auxiliary 20 mA regulator (pin 32) is available for

additional system circuits.

Data transmission comprises low level encoding for

ISO15693, modified Miller for ISO14443-A,

high-bit-rate systems, Tag-it, and HF-EPC system

coding. Included with the data encoding is automatic

generation of SOF, EOF, CRC, and/or parity bits.

The receiver system enables AM and PM

demodulation using a dual-input architecture. The

receiver also includes an automatic gain control

option and selectable gain. Also included is a

selectable bandwidth to cover a broad range of input

sub-carrier signal options. The received signal

strength for AM and PM modulation is accessible via

the RSSI register. The receiver output is selectable

between a digitized sub-carrier signal and any of

eleven integrated sub-carrier decoders (two for

ISO15693 low bit rate, two for ISO15693 high bit

rate, two for ISO14443, three for ISO14443 high bit

rates, one for Tag-it, and one for HF-EPC system).

Selected decoders also deliver bit stream and a data

clock as outputs.

(1) The absolute maximum ratings under any condition is limited by the constraints of the silicon process. Stresses above these ratings may

cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are

stress ratings only and functional operation of the device at these or any other conditions beyond those specified are not implied

(2) The maximum junction temperature for continuous operation is limited by package constraints. Operation above this temperature may

result in reduced reliability and/or lifetime of the device.

(2) Power rating is determined with a junction temperature of 125°C. This is the point where distortion starts to substantially increase.

Thermal management of the final PCB should strive to keep the junction temperature at or below 125°C for best performance and long
