MLX72013
433MHz
FSK/ASK Transmitter
5. General Description
The MLX72013 transmitter IC is designed for applications in the European 433 MHz industrial-scientific-
medical (ISM) band, according to the EN 300 220 telecommunications standard; but it can also be used in
any other country with similar frequency bands.
The transmitter's carrier frequency f_c is determined by the frequency of the reference crystal f_ref. The
integrated PLL synthesizer ensures that each RF value, ranging from 425 MHz to 445 MHz, can be achieved
by using a crystal with a reference frequency according to: f_ref = f_c/N, where N = 16 is the PLL feedback
divider ratio.
