AM / FM-PLL
Description
The U4286BM is an integrated circuit in BICMOS
technology for frequency synthesizer. It performs all the
functions of a PLL radio tuning system and is controlled
by I
2
C bus. The device is designed for all frequency
synthesizer applications of radio receivers, as well as
RDS (
R
adio
D
ata
S
ystem ) applications.
Features
Reference oscillator up to 15 MHz
Two programmable 16 bit dividers
adjustable from 2 to 65535
Fine tuning steps: AM
1 kHz
2 kHz
FM
Two programmable switching outputs (open drain up
to 20 V)
Few external component requirements due to
integrated loop-transistor for AM/FM
High signal/ noise ratio
