1 / 5 page BU1924 / BU1924F Audio ICs RDS / RBDS decoder BU1924 / BU1924F The BU1924 and BU1924F are RDS / RBDS decoders that employ a digital PLL and have a built-in anti-aliasing filter and an eight-stage BPF (switched-capacitor filter). Linear CMOS circuitry is used for low power consumption. ! ! ! ! Applications RDS / RBDS compatible FM receivers for American and European markets, car stereos, high-fidelity stereo systems and components, and FM pagers. ! ! ! ! Features 1) Low current. 2) Two-stage anti-aliasing filter (LPF). 3) 57kHz band-pass filter. 4) DSB demodulation (digital PLL). 5) Quality indication output for demodulated data. ! ! ! !
