2.1 Overview
2.2 Applications
2.3 Features
The TDK 5101 is a single chip ASK/FSK transmitter for the frequency band 311-
317 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 and a divided clock output are implemented. The IC can be used
for both ASK and FSK modulation.
