General Description

The TH72016 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 other countries with similar standards,

e.g. FCC part 15.231.

ensures that carrier frequencies, ranging from 380 MHz to 450 MHz, can be achieved. This is done by using a crystal with a

A clock signal with selectable frequency is provided. It can be used to drive a microcontroller.
