TDA7100 - Infineon

Product Brief
TDA 7100
T h e T D A 7 1 0 0 i s a s i n g l e c h i p A S K / F S K t r a n s m i tt e r
operating in the 433 to 435MHz frequency band. The IC offers a high level of
integration and needs only a few external components to build a complete
transmitter. The device contains a fully integrated PLL 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 ( Fref ÷16 ) which
could be used as CLK for a µC.
