AN7261FBQ
FM multiplex reception IC
s Overview
The AN7261FBQ is an FM-multiplex reception IC
including a front-end and an IF block for FM tuner. Since
the receiving circuit of FM multiplex signal is integrated
on a single chip, it is most suitable for saving the space of
sets.
s Features
• A single chip IC for an FM-multiplex tuner block, which
was conventionally composed of two ICs.
• Fewer external components
• Can be used for 15 MHz IF
s Applications
• VICS, RDS
