1.1
Overview
The TDK 5100 is a single chip ASK/FSK transmitter for the frequency bands
433-435 MHz and 868-870 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. Additional features like
a power down mode, a low power detect, a selectable crystal oscillator fre-
quency and a divided clock output are implemented. The IC can be used for
both ASK and FSK modulation.
