General Description
The BK1089 single-chip FM receiver employs
a low-IF architecture, mixed signal image
rejection and all digital demodulation
technology. The station scan of BK1089
searches radio stations based on both the
channel RSSI estimation and signal quality
assessment, increases the number of receivable
stations while avoids false stops. BK1089
enables FM radio reception with low power,
small board space and minimum number of
external components.
