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 fc is determined by the frequency of the reference crystal fref. 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: fref = fc/N, where N = 32 is  
the PLL feedback divider ratio.
