Thick Film Hybrid IC
STK311-020
RDS Demodulator with Synchronization
and Error Correction
Overview
The STK311-020 is an RDS demodulator hybrid IC for the
Radio Data System (RDS), or multiplexed FM broadcast-
ing of various kinds of data, specified by the European
Broadcasting Union (EBU). It demodulates the multiplexed
data modulating signal to recover the RDS signal and per-
forms synchronization, error detection and error correction,
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
• Home stereos
Features
• 57kHz BPF built-in for adjustment-free operation
• 4MHz ceramic oscillator element built-in
• Few external components required for a complete RDS
data demodulation system
• ARI-SK/DK decodrer built-in
