2
with the express written approval of the
Infineon Technologies AG.
1 A critical component is a component used in a life-support device or system whose failure can reasonably be expected to cause the failure of that life-
support device or system, or to affect its safety or effectiveness of that device or system.
2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain and sustain human life. If they
fail, it is reasonable to assume that the health of the user may be endangered.

Product Info
General Description
The TDK 5110 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 inte-
gration 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. Addi-
tionally 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.
