The STK311-010 is a hybrid integrated circuit (HIC) for Radio Data System (RDS) applications which must conform to European Broadcasting Union (EBU) enforced recommendations. Since the Radio Data System (RDS) subjects every kind of data to multiplex broadcasting for FM broadcasts, the STK311-010 functions as a hybrid IC which demodulates the modulated signal's data, previously multiplexed to a RDS signal, matches synchronization and performs error detection and correction. By combining SC system and photoresist technology with folded board construction and incorporating Sanyo's unique insulated metal substrate technology (IMST) to the base, the STK311-010 has successfully been contained within a low-profile package.
