STK311-120

The STK311-120 is designed as RDS demodulator hybrid IC for the ratio data system (RDS), or multiplexed FM broad-casting of various kinds of data, introduced within the european broadcasing union (EBU). It demodulates the multiplexed data modulating signal to recover the RDS signal. It typical applications include car stereos, home stereos.

STK311-120 has four features. (1) Smaller width package dimension (35mm max) than the STK311-110. (2) 57kHz BPF built-in for adjustment free operation. (3) Few external components required for a complete RDS data demodulation system. (4) ARI-SK / DK decoder built-in. That are all the main features.

Some absolute maximum ratings of STK311-120 have been concluded into several points as follow. (1) Its maximum supply voltage would be 6.3V. (2) Its operating temperature range would be from -30°C to +85°C. (3) Its storage temperature range would be from -40°C to +100°C. (4) Its resommended supply voltage would be 5V. (5) Its recommended operating supply voltage range would be from 4.7V to 5.5V.

Also some operating characteristics about STK311-120. (1) Its quiescent current would be typ 22mA and max 30mA. (2) Its band pass filter gain would be min 9dB and typ 12.5dB and max 17dB. (3) Its center frequency would be min 55.8kHz and typ 57lHz and max 58.2kHz. (4) Its band pass filter selectivity would be min -50dB and typ -38dB and max -20dB at 90kHz and min -4dB and typ -2.5dB and max 0dB at 60kHz and would be min -50dB and typ -39dB and max -35dB at 38kHz. (5) Its RDS detector sensitivity would be min 0.15mVrms and typ 0.4mVrms and max 1.0mVrms. (6) Its SK detector sensitivity would be min 0.3mVrms and typ 1.0mVrms and max 2.0mVrms. And so on.
