    3.2.1 Functional Description of the PLL’s The G600 design employs two fixed IF LO’s - 201MHz for Rx and 246MHz for Tx. They are generated at 402MHz and 496MHz using the IF part of the PLL IC. The IF VCO used is a discrete design and the VCO tuning frequency is selectable between 402MHz and 492MHz by means of switching the frequency determining inductors, L302+L303, by IFLOSEL control line.

  • Page 23: Functional Description

    Functional Description The G600 baseband is based around a 2 chip GSM chipset. One chip carries out signal processing with DSP and CPU, called GEMINI, and the other chip contains the analogue interface chip, called VEGA. The highly integrated nature of these components means each contain a large number of functions.
  • Page 24 BASEBAND OVERVIEW 6.2.1 Keypad The Keypad has a 5 x 5 matrix allowing 25 keys to be scanned on a key being pressed, a keypad interrupt is generated. To find which key is pressed the software must assert each column in turn and read which row is active. Because of key bounce, the key press must then be confirmed twice at about 20mS intervals.

  • Page 35: Power-Up

    POWER SUPPLIES Signal CPU I/O Description External interrupt to the CPU. The voltage detector output goes LOW when the battery voltage drops below 3.6V. If the phone is on, this signal forces the PSU off and the interrupt initiates an emergency power down procedure. If the phone is off, a LOW on this signal will lock the PSU off.

  • Page 36: Power-Down

    POWER SUPPLIES 9.3.2 Power-up Sequence The power-up sequence can be initiated by pressing the power key or by the presence of an external power source on the signal EXT_PWR. Both enable the linear regulators and the CPU becomes active. The CPU must then check the battery condition;...

  • Page 37: Power Management

    The Power supply circuit needs to supply regulated power to the baseband and RF parts, control battery charging and monitor battery usage. G600 must achieve 2 types of battery operation - 4 cell Ni-MH and 2 cell Li-ION. The power supply section consists of four parts;...
  • Page 38 POWER SUPPLIES NOTE: During charging, the voltage could rise as high as 9.4V and all circuitry connected to the battery must be designed to operate up to this voltage. A block diagram for a four cell power supply is shown in figure 2 below, note that the battery voltage is stepped-up to power 5V SIM cards or the 5V RF power amplifier.

  • Page 39: Voltage Regulation

    Especially in Li-ION cells, high voltage dropout reduces the efficiency more than a small voltage dropout. To increase the current consumption efficiency, the G600 uses 3.4V step-down DC/DC voltage regulators. The DC/DC step-down circuitry uses two regulators on the LOGIC side and three regulators on the RF side to reduce the power loss to minimum.
  • Page 40 POWER SUPPLIES 9.5.2 Battery Charging circuit The CPU within the phone controls the battery charging. When external power is present the phone is automatically switched on. If rechargeable cells are detected and the temperature is within specified limits the charger starts using a rapid charge algorithm.
