NSB-9 System Module and User Interface CCS Technical Documentation Baseband Functional Description Modes of Operation NSB-9 baseband has six different functional modes: • No supply • Back-up • Acting Dead • Active • Sleep • Charging No supply In NO_SUPPLY mode the phone has no supply voltage. This mode is due to disconnection of main battery and backup battery or low battery voltage level in both of the batteries.
NSB-9 System Module and User Interface CCS Technical Documentation One of the sub-state of the active mode is FM radio on state. In that case UEM audio blocks, stereo amplifier and FM radio are powered on. FM radio circuitry is controlled by the MCU and 32kHz reference clock is supplied by the UPP. VFLASH2 regulator is operating. In active mode the RF regulators are controlled by SW writing into UEM’s registers wanted settings: VR1A can be enabled or disabled.
NSB-9 System Module and User Interface 4 CCS Technical Documentation RTC Alarm, the RTC has been programmed to give an alarm After receiving one of the above signals, the UEM counts a 20ms delay and then enters it’s reset mode. The watchdog starts up, and if the battery voltage is greater than Vcoff+ a 200ms delay is started to allow references etc. to settle. After this delay elapses the VFLASH1 regulator is enabled. 500us later VR3, VANA, VIO and VCORE are enabled.
NSB-9 System Module and User Interface CCS Technical Documentation Power up when battery is connected Baseband can be powered up by connecting battery with sufficient voltage. Battery voltage has to be over UEM internal comparator threshold level, Vcoff+. Battery low limit is specified in Table 2. When proper battery voltage is detected UEM enters to reset sequence as described earlier.
NSB-9 System Module and User Interface CCS Technical Documentation FM Radio FM radio circuitry used in NSB-9 is a single-chip electronically tuned FM stereo radio with fully integrated IF selectivity and demodulation. The radio is completely adjustment-free and does only require a minimum of small and low cost external components. It has signal dependent mono/stereo blend [Stereo Noise Cancelling (SNC)]. The radio can tune the European, US and Japan FM bands.
NSB-9 System Module and User Interface CCS Technical Documentation FM-radio audio connections FM-radio audio output signals are fed to stereo audio amplifier Rin and Lin inputs and UEM microphone input MIC3. Amplification of the audio signal is made by the audio circuitry inside the UEM (IHF mode) and stereo audio amplifier. In IHF mode the left audio signal is looped internally in UEM from MIC input to XEAR output, which is connected to stereo audio amplifier Phone input (Phone InHS and Phone InIHF).

NSB-9 System Module and User Interface CCS Technical Documentation Internal Speaker The internal earpiece is mounted into the LCD metal frame. The earpiece is a dynamic earpiece with a 32 ohm impedance. The earpiece is low impedance one since the sound pressure is to be generated using current and not voltage as the supply voltage is restricted to 2.7V. The earpiece is driven directly by the UEM. The earpiece driver in UEM is a bridge amplifier.
