TDA7110F

The TDA 711x(F) products are single chip ASK/FSK transmitter operating in the 434 and 868MHz frequency band. The ICs offer a high level of integration and need only a few external components to build a complete transmitter solution. The products vary in package and supported frequency band. The devices contain a fully integrated PLL synthesizer and a high efficiency power amplifier to drive the antenna. A special circuit design, a unique power amplifier and a power down feature contribute to low current consumption and to extended battery life. The ICs have a clock output for the micro-controller and as such enable the usage of only one crystal in the application. Additionally, TDA 7110 features a selectable clock divider ratio.
