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 ranging from 290 MHz to 350 MHz.

The transmitter TH72001's carrier frequency fc is determined by the frequency of the reference crystal fref. The integrated 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: fref = fc/N, where N = 32 is the PLL feedback divider ratio.
