Melexis TH72015
The TH72015 FSK/ASK transmitter IC is designed for applications in the European 433 MHz industrialscientific-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. The transmitter's carrier frequency fc is determined by the frequency of the reference crystal fref. The integrated PLL synthesizer ensures that carrier frequencies, ranging from 380 MHz to 450 MHz, can be achieved.| Part No. | TH72015 |
