General Description

The TH72005 FSK/ASK transmitter IC is designed for applications in the 315 MHz industrial-scientific-

medical (ISM) band. It can also be used for any other system with carrier frequencies ranging from

290 MHz to 350 MHz.

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 290 MHz to 350 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.
