General Description
The BK1086/88 AM/FM receiver employs a
low-IF architecture, mixed signal image
rejection and all digital demodulation
technology. The station scan of BK1086/88
searches radio stations based on both the
channel RSSI estimation and signal quality
assessment, increases the number of receivable
stations while avoids false stops. BK1086/88
enables FM/AM/SW/LW radio reception with
low power, small board space and minimum
number of external component.
