2.1 FM grazing device

The FM receiver adopts a digital low-IF architecture that can reduce the number of peripheral components. The internal part is a low-noise amplifier (LNA) that supports the world's FM broadcasting band (60-112MHz) , The automatic gain FM broadcasting band (60-112MHz) , The automatic gain FM broadcasting band (60-112MHz) , The automatic gain controller (AGC) that can control the gain of the LNA to optimize sensitivity and suppress large interference signals, and the image rejection trickler that can convert radio frequency signals into low-IF signals. The output of the mixer passes Onefrequency signals into low-IF signals. The output of the mixer passes One A programmable gain control amplifier (PGA) to amplify, and then One A high-resolution analog-to-digital converter (ADC) then One A high-resolution analog-to-digital converter (ADC) then One A high-resolution analog-to-digital converter (ADC) converts into a digital signal. An audio digital signal processor (CDSP) completes the functions of channel selection, FM demodulation, stereo multiplexer and output audio signal . Multi-channel demodulation, stereo multiplexer and output audio signal . Multi-channel demodulation, stereo multiplexer and output audio signal . Multi-channel decoder can automatically convert from stereo to mono decoding ,decoding , This limits the output noise.

2.2 Medium-Polish pastoralist

BK1198 supports the worldwide AM frequency band (504-l 750kHz) through 3 bands. It uses a low-IF architecture to minimize the number of peripheral devices. Using this architecture can achieve high-precision filtering, thereby achieving excellent sensitivity and noise suppression. Similar to the FM receiver, the AM receiver is woven into LNA and AGC, which optimizes sensitivity and suppresses large interference signals, so that weak signal stations can also have good reception. BK1198 provides high-accuracy digital AM automatic tuning, thus eliminating the need for production line debugging. In order to provide maximum flexibility, the receiver can support the magnetic rod line circle in the range of 180~300µH for the thousand medium wave Proprietary and Confidential Page 3 of 28 Page 3 of 28 Page 3 of 28 Page 3 of 28

2.7 Band selection

BK1198 supports 4 kinds of band selection methods. Method 1: Select by externally connecting the BAND pin and the voltage divider resistor network between the TUNE l pin Ren One BandRen One BandRen One Band Method 2: Select the band by externally connecting the BAND pin and the voltage divider resistor network between the TUNE l pin and connecting the AM/FM pin with a single key switch. Proprietary and Confidential Page 4 of 28

Method 3: Select the band by externally connecting the BAND pin and the voltage divider resistor network between the TlJNF1 pin and connecting the two key switches of the AM/FM pin. Method 4: External MCU control selection. BK1198 uses band selection method 1 by default. If other methods are used, MTP must be configured first. For detailed peripheral circuit design, please refer to the application document.
