General Description

The XE1218 is a single chip ultra low-power VHF

FM receiver. The circuit includes the RF receiver

section, the demodulator and the audio amplifier

that is directly connected to an external earpiece. It

uses analog narrow-band FM modulation.

The XE1218 is based on a low-IF architecture, with

on-chip channel filter and a delay line type

demodulator.

The LO is generated by a crystal oscillator.
