Introduction

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 fc is determined by the frequency of the reference crystal fref. 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: fref = fc/N, where N = 16 is the PLL feedback divider ratio.
