LV25200M
Bi-CMOS IC
Single chip Tuner IC for Car Radio
Overview
LV25200M is a tuner IC for car radio, which incorporates the AM/FM Tuner, PLL, AM/FM Noise Canceller (NC), FM
Stereodecoder (MPX) , Multipath-noise Rejection Circuit (MRC) .
This IC enables development of the low-cost analog tuner for OEM.
Functions
• AM+FM-FE+IF+NC+MPX+MRC+PLL
Features
• World-wide compatible tuners
A single tuner module is enough to supply the world-wide compatible tuners.
FM is compatible with US EURO, Japan bands while AM is compatible with LW, MW, SW, Weather-Band.
With the image cancel mixer incorporated in FM MIX, the external RF AMP can be deleted.
Compatible with RDS. PLL fast locking.
• Self-contained type IF band variable filter incorporated
Detects any neighboring interfering station and varies the IF filter band, enabling superior selectivity characteristic.
• Auto alignment EEPROM necessary
FM RF, VCO, Null-voltage, Mute-on, Mute-ATT, SNC, HCC, Station detector, Gain AGC sensitivity,
CCB bus compatible
• Reduced parts quantity
Parts quantity reduced from our conventional products
• Other functions
AM noise canceller (genuine compatible)
• CCB is a registered trademark of SANYO Electric Co., Ltd.
• CCB is SANYO Semiconductor's original bus format. All bus addresses are managed by SANYO

Discription
FM:
PLL filter formed with pins 9 to 12
(Pins 10 and 11 to be left OPEN)
AM:
PLL filter formed with pins 10 and 11. In this case,
the low pass filter is formed with the internal
impedance (100kΩ) and external capacity.
11 Charge pump for FM Simultaneous use of AM and FM filters (pins 9 to
12) is possible through mode changeover. In this
case, internal impedance (100kΩ) is short-circuited.

VCO monitor (at IN3-5 D6=H)
Saw-tooth wave of MPX-VCO frequency is output,
which is monitored for VCO adjustment
(Adjust with IN3-5 D0-5.)
15 Separation adjustment The input level of sub-decoder is varied through
pin BIT control.
(The output level of MONO and MAIN remains
unchanged.)
