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.
