TDA7100

The TDA 7100 is a single chip ASK/FSK transmitttter operating in the 433 to 435MHMHz frequency band. The ICIC offers a high level of integration and needs only a few external components to build a complete transmitter. The device contains a fully integrated PLLLL synthesizer and a high efficiency power amplifier to drive the antenna. A special circuit design and a unique power amplifier contribute to low current consumption and to extended battery life. Additional features are a power down mode and a clock output ( F ref ÷16 ) which could be used as CLCLK for a μC.
