Application Note
CMOS LSI
FM multiple tuner IC
Overview:
http://onsemi.com
LC01707PLF is a vehicle-mounted FM multiple tuner IC with FM-FE, IF, IF-Filter, PLL, FM-DEMO and LPF
incorporated. An FM multiple tuner can be developed with this one chip. It makes up a small-sized FM
multiple tuners which can be mounted on PND.
Functions:
It is the FM tuner IC exclusively for the FM multiple. LNA is incorporated
Image reduction complex BPF is incorporated
Wide / Narrow Band RF AGC is incorporated
Narrow Band IF AGC is incorporated
Image rejection is adopted
DLL detection method is adopted for the FM detection circuit, and it is not necessary to adjust.
LPF for the carrier removal is incorporated.
IC requires fewer external components.
It is a BUS control tuner IC which can be controlled by controlled by I2C BUS.
Typical Applications:
DARC tuner for AVN, PND and Car Audio System
RDS tuner for AVN, PND and Car Audio System
SCA tuner for AVN, PND and Car Audio System
