LV23401V
Bi-CMOS IC
1-chip Tuner IC with built-in FLL
for Home Stereo System
http://onsemi.com
Overview
The LV23401V is a AM/FM one-chip tuner IC for home stereo system.
Functions
AM tuner
FM tuner
MPX stereo decoder
FLL tuning system
Features
All the adjustment work of external parts is unnecessary.
CCB control with easy command base
External parts are reduced by LOW-IF frequency (FM=225kHz, AM=53kHz) adoption.
The high sensitivity reception is achieved in low noise MIX input circuit.
All bands of Japan-U.S.-Euro can be received by the soft program change (76MHz to 108MHz).
With built-in FLL(Frequency Locked Loop) tune function
Soft mute and stereo blend function (seven stages programmed control possible)
With built-in adjacent channel obstruction removal function
With built-in stereo pilot cancellation function
For EN55020-S1 standard (European immunity)
With built-in power save function
