System Module
The Bluetooth module (D6000) is a single chip solution that uses common clock signal (38.4 MHz) with WLAN
module. BT has interfaces to modem ASIC D2800 (PCM for BT audio), application ASIC D4800 (UART for BT
data) and to WLAN, which controls antenna usage.
FM radio
The FM radio is and integrated circuit, controlled by MCU software through a serial bus interface. The wires
of the headset are used as poles of the antenna, and no other antenna is needed for FM radio reception. The
FM radio utilizes the AV connector for its antenna connectivity. The RF input of the FM radio module is
connected to the stereo audio output pins (HS_EAR_L/R) via RF coupling circuitry. Wired headset connected
to the AV connector works as an antenna for FM radio. The FM radio is controlled by I2C commands from
RAPIDO. The audio output of the FM radio (D6000) is fed to the headset via EM ASIC N2200.
