The STK311-110 is an RDS demodulator hybrid IC for the Radio Data System (RDS), or multiplexed FM broadcasting 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 constructed. 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.
