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

any other country with similar frequency bands.

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

integrated PLL synthesizer ensures that each RF value, ranging from 380 MHz to 450 MHz, can be achieved

by using a crystal with a reference frequency according to: f_ref= f_c/N, where N = 32 is the PLL feedback

divider ratio.
