General Description

The TH72001 FSK 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 at

290 to 350MHz.

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

integrated PLL synthesizer ensures that the radio frequency (RF) 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.
