The BU1920, BU1920F and BU1920FS are RDS / RBDS decoders that employ a digital PLL. It has a built-in anti-aliasing filter and an eight-stage BPF (switched-capacitor filter). Linear CMOS circuitry is used for low current dissipation. Features 1) Low current dissipation. 2) Two-stage anti-aliasing filter. 3) 57kHz bandpass filter. 4) DSB demodulation (digital PLL). 5) ARI signal discrimination. 6) Quality indication output for demodulated data. Applications RDS/RBDS compatible FM receivers for Europe and North America, car stereo systems, home stereo systems and FM pagers.
