| Ordering number: EN 4588A Thick Film Hybrid IC STK311-110 RDS Demodulator Overview 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. Package Dimensions unit: mm 4142 [STK311-110] Applications * Car stereos * Home stereos Features * 57kHz BPF built-in for adjustment-free operation * Few external components required for a complete RDS data demodulation system * ARI-SK/DK decoder built-in Specifications Maximum Ratings at Ta = 25C Parameter Maximum supply voltage Operating temperature Storage temperature Symbol VCC max Topr Tstg Ratings 6.3 -30 to +85 -40 to +100 Unit V C C Recommended Operating Voltages at Ta = 25C Parameter Supply voltage Operating supply voltage range Symbol VCC VCCOP Ratings 5 4.7 to 5.5 Unit V V SANYO Electric Co., Ltd.
