Product Description

2.1 Overview

The TDA5110 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 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.
