Product Description

2.1 Overview

The TDA 5103A is a single chip ASK transmitter for the frequency band 344-

347 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.
