DESCRIPTION

The TK83361M is a narrow band FM IF IC designed for

cordlessphones,radiotransceivers,remotecontrols,wire-

less data transceivers, and other communication equip-

ment.

RF INPUT

It integrates the mixer, oscillator, limiting amplifier, FM

demodulator,filteramplifierandsquelchcircuitintoasingle

surface mount SOP-16 package. The low operating cur-

rent combined with a minimum operating voltage of only 2

V makes this device ideal for battery powered devices.

IF INPUT

The TK83361M offers improved performance over the

MC3361C.Theoperatingfrequencyhasbeenincreasedto

220MHz (vs. 60MHz) while reducing the supply current

from 5.2 mA to 3.8mA (squelch on). Offered in the SOP-16

surface mount package, the TK83361M is a drop-in re-

placement for the MC3361C.
