BU1920 Datasheet, PDF (1/7 Pages) Rohm – RDS / RBDS decoder

Audio ICs
RDS / RBDS decoder
BU1920 / BU1920F / BU1920FS
The BU1920, BU1920F and BU1920FS are RDS / RBDS decoders that employ a digital PLL. It has a built-in anti-alias-
ing filter and an eight-stage BPF (switched-capacitor filter). Linear CMOS circuitry is used for low current dissipation.
FApplications
RDS / RBDS compatible FM receivers for Europe and North America, car stereo systems, home stereo systems and FM
pagers.
FFeatures
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.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
