DESCRIPTION
The TK83361M is a narrow band FM IF IC designed for
cordless phones, radio transceivers, remote controls, wire-
less data transceivers, and other communication equip-
ment.
It integrates the mixer, oscillator, limiting amplifier, FM
demodulator, filter amplifier and squelch circuit into a single
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.
The TK83361M offers improved performance over the
MC3361C. The operating frequency has been increased to
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.
