Product Descriptions

The BK1080 FM 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 RSSI estimation and 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. The device operates from a power supply of 2.7 – 5.5 volts.

The BK1080 is available in both 24-pin 4x4 mm QFN and SOP16 package.
