General Description
The TDA7110 is a single chip ASK/FSK ^Package
transmitter for the frequency bands
868-870 MHz and 433-435 MHz. The
IC offers a high level of integration and
needs only a few external 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 there-
fore to save battery life. Additionally
features like a power down mode, a low
power detect, a selectable crystal oscil-
lator frequency and a divided clock out-
put are implemented. The IC can be
used for both ASK and FSK modula-
tion.
