BK1080SB datasheet


The BK1080 FM stereo receiver employs a low-IF architecture, mixed signal image rejection and all digital demodulation technology. The station scan of BK1080 searches radio stations based on both the channel SNR estimation and demodulated signal quality assessment, increases the number of receivable stations while avoids false stops. BK1080 enables fm radio reception with low power, small board space and minimum number of external components. All functions are controlled through a simple 3-wire serial interface or I2C serial interface.
