    UEM generates 100mA constant output current from the connected charger's output voltage. As battery charges, its voltage rises and when VBAT voltage level is detected to be higher than the master reset threshold limit (VMSTR+), START_UP charge is terminated. ©2003 Nokia Corporation Page 8 Confidential Issue 1 11/2003...

    RH-34 Baseband is powered from five different UEM regulators: VANA, VIO, VFLASH1, VFLASH2, and VCORE DC/DC. See Table 1. UEM voltage regulators: VR1A, VR1B, VR2, VR3, VR4, VR5, VR6 and VR7 are used by RF. See Table 2. ©2003 Nokia Corporation Page 10 Confidential Issue 1 11/2003...

  • Page 11: Clock Distribution

    The main clock signal for the baseband is generated from the voltage and temperature controlled crystal oscillator VCTCXO (G503). This 19.2 MHz clock signal is generated at the RF and fed to RFCLK pin of UPP. ©2003 Nokia Corporation Issue 1 11/2003 Confidential...
