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

integrated PLL synthesizer ensures that each RF value, ranging from 290 MHz to 350 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.
