Target Application Frequencies for TDA5230 and TDA5231
The TDA523x family of receivers cover a wide range of commonly used receive
frequencies within the three major ISM-bands used in TPMS, RKE/PKE and remote
control system applications.
The TDA5230 covers operation in the 433..450 MHz and 865..868 MHz ISM bands. The
TDA5231 covers complementary operation in the 302..320 MHz ISM-band.
Figure 1 identifies the capabilities of the TDA5230 and TDA5231 within the three
different frequency bands.
