DESCRIPTION
The TK83361M is a narrow band FM IF IC designed for
cordless phones, radio transceivers, remote controls, wireless data transceivers, and other communication equipment.
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 current 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 replacement for the MC3361C.

n Amateur Radio Transceivers
n Cordless Phones
n Remote Controls
n Wireless Data Transceivers
