The BU1923 and BU1923F 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.

特性 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.

Applications

RDS / RBDS compatible FM receivers for American and

European markets, car stereos, high-fidelity stereo systems

and components, and FM pagers.
