Product Summary
The 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 FSK signal (frequency shift keyed). 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 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.
