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)
