TH71072 General Description
The TH71072 ASK transmitter IC is designed for applications in the European 433MHz industrialscientific- medical (ISM) band, according to the EN 300 220 telecommunications standard. It can also be used for any other system with carrier frequencies ranging from 310 MHz to 440 MHz (e.g. for applications in the US 315MHz ISM band).
The transmitter's carrier frequency fc is determined by the frequency of the reference crystal fref that is used. The integrated PLL synthesizer ensures that each RF value, ranging from 310 MHz to 440 MHz, can be achieved by using a crystal with reference frequency according to: fref = fc/N, where N = 32 is the PLL feedback divider ratio.
