General Description
The TDA 5103A is a single chip ASK ^Package
transmitter for the frequency band 344-
347 MHz. The IC offers a high level of
integration and needs only a few exter-
nal components. The device contains a
fully integrated PLL synthesizer and a
high efficiency power amplifier to drive
a loop antenna. A special circuit design
and an unique power amplifier design
are used to save current consumption
and therefore to save battery life. Addi-
tionally features like a power down
mode, a low power detect and a divided
clock output are implemented.
