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.
