XE1218A

Low power single die FM receiver

General Description

The XE1218 is a single die, low power, FM

receiver operating in the VHF band from 130MHz

to 230MHz. Its highly integrated architecture allows

for RF and audio functions on the same die, whilst

minimizing the external components needed to

build a complete application at the same time.

The XE1218A enables single chip, complete audio

transmission solutions, where the antenna feeds

the incoming RF signal directly into the XE1218A

and an amplified audio signal can be fed to an

earphone directly from the XE1218A’s output.

Flexibility has been built into the XE1218A: various

different transmission channels can be selected,

the audio output can also be fed to a post

processing circuit such as sound de-emphasis or

an external power amplifier.

The XE1218A is optimized for battery powered

applications, it can be operated directly on one

lithium 1.5V battery cell.
