General Description

The TH72012 ASK transmitter IC is designed for applications in the European 433 MHz industrial-scientific-

medical (ISM) band, according to the EN 300 220 telecommunications standard; but it can also be used in

other countries with similar standards, e.g. FCC part 15.231.

The transmitter's carrier frequency f_cis determined by the frequency of the reference crystal f_ref. The inte-

grated PLL synthesizer ensures that carrier frequencies, ranging from 380 MHz to 450 MHz, can be

achieved. This is done by using a crystal with a reference frequency according to: f_ref= f_c/N, where N = 32 is

the PLL feedback divider ratio.
