3 Description

The TMS3705 transponder base station IC is used to drive the antenna of a TI-RFid transponder system, to

send data modulated on the antenna signal, and to detect and demodulate the response of the transponder.

The response of the transponder is a frequency shift keyed (FSK) signal. The high or low bits are coded in two

different high-frequency signals (134.2 kHz for low bits and 123 kHz for high bits, nominal). The transponder

induces these signals in the antenna coil according an internally stored code. The energy that the transponder

needs to send out the data is stored in a charge capacitor in the transponder. The antenna field charges this

capacitor in a preceding charge phase. The IC has an interface to an external microcontroller.

There are two configurations for the clock supply to both the microcontroller and the base station IC:

1. The microcontroller and base station IC are supplied with a clock signal derived from only one resonator:

The resonator is attached to the microcontroller. The base station IC is supplied with a clock signal driven by

the digital clock output of the microcontroller. The clock frequency is either 4 MHz or 2 MHz, depending on

the selected microcontroller type.

2. The microcontroller and the base station each have their own resonator.

The base station IC has an on-chip PLL that generates a clock frequency of 16 MHz for internal

clock supply only. Only TMS3705DDRQ1 and TMS3705GDRQ1 is recommended in combination with AES

transponder products (for example, TRPWS21GTEA or RF430F5xxx). TMS3705EDRQ1 and TMS3705FDRQ1

is recommended for best performance in combination with DST40, DST80, MPT transponders (for example,

TMS37145TEAx, TMS37126xx, TMS37x128xx, TMS37x136xx, TMS37x158xx, RI-TRP-DR2B-xx, RI-TRPBRHP-

xx) and cannot be used in combination with AES transponder products.
