General Description

The TDK 5101 is a single chip ASK/ Package

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 con-

tains 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 con-

sumption and therefore to save battery

life. Additionally 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.
