CCS Technical Documentation 5 Sleep 6 Charging Company confidential RH-23 System Module and User Interface 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. Phone is exiting from NO_SUPPLY mode when sufficient battery voltage level is detected.
RH-23 Company confidential System Module and User Interface CCS Technical Documentation The sleep mode is exited either by the expiration of a sleep clock counter in the UEM or by some external interrupt, generated by a charger connection, key press, headset connection etc. In sleep mode VCTCXO is shut down and 32 kHz sleep clock oscillator is used as reference clock for the baseband. Charging Charging can be performed in parallel with any operating mode.
CCS Technical Documentation Company confidential RH-23 System Module and User Interface Power Up with PWR key When the Power on key is pressed the UEM enters the power up sequence as described in the previous paragraph. Pressing the power key causes the PWRONX pin on the UEM to be grounded. The UEM PWRONX signal is not part of the keypad matrix. The power key is only connected to the UEM. This means that when pressing the power key an interrupt is generated to the UPP that starts the MCU.
RH-23 Company confidential System Module and User Interface CCS Technical Documentation A/D Channels The UEM contains the following A/D converter channels that are used for several measurement purposes. The general slow A/D converter is a 10-bit converter using the UEM interface clock for the conversion. An interrupt will be given at the end of the measurement. The UEM’s 11-channel analog to digital converter is used to monitor charging functions, battery functions, user interface and RF functions.

Company confidential RH-23 System Module and User Interface CCS Technical Documentation RF Module Introduction The RF module performs the necessary high frequency operations of the EGSM900/ GSM1800 dual band (EDGE) engine. Both the transmitter and receiver have been implemented by using direct conversion architecture, which means that the modulator and demodulator operate at the channel frequency. The core of the RF is an application-specific integrated circuit, Helgo.
RH-23 Company confidential System Module and User Interface CCS Technical Documentation RF Frequency Plan RF frequency plan is shown below. The VCO operates at the channel frequency multiplied by two or four depending on the frequency band of operation. This means that the baseband-modulated signals are directly converted up to the transmission frequency and the received RF signals directly down to the baseband frequency. Figure 21: RF Frequency plan Page 40 Nokia Corporation.
