Thick Film Hybrid IC
RDS Demodulator
Overview
The STK311-110 is an RDS demodulator hybrid IC for
the Radio Data System (RDS), or multiplexed FM broad-
casting of various kinds of data, introduced within the
European Broadcasting Union (EBU). It demodulates the
multiplexed data modulating signal to recover the RDS
signal. In combination with an LC7070 series LSI (for
sync handling, error detection and correction), a low-cost
high-performance RDS data decode system can be con-
structed. Further, low-profile packaging is realized using
Sanyo's insulated metal substrate technology (IMST) for
the base, SC system and photoresist technologies and
folded board construction.
Applications
Car stereos
