The TDK5110 is a single chip ASK/
FSK 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 therefore to save battery life. Additionally
features like a power down
mode, a low power detect, a selectable
crystal oscillator frequency and a
divided clock output are implemented.
The IC can be used for both ASK and
FSK modulation.
