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.
