General Description

The TH72015 FSK/ASK 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.

synthesizer ensures that each RF value, ranging from 380 MHz to 450 MHz, can be achieved by using a crystal with a
