Operational Modes
There are several different operational modes, which have different states controlled by
the cellular SW. Some examples are: Idle State (on ACCH), Camping (on DCCH), Scanning,
Conversation, and No Service Power Save (NSPS).
• Power-off mode = Only the circuits needed for power-up are supplied.
• Sleep mode = Circuits are powered down and only the 32kHz sleep clock runs. In
slotted mode or idle mode (a combination of sleep mode and receive mode), some
circuits turn on during the wake-up slot to receive page messaging from the base
station.
• Active mode = All circuits are supplied with power, although some parts might be
in idle state part of the time.
• Charge mode = Effective in parallel with all previous modes. The charge mode
itself consists of two different states, the fast charge and the maintenance mode.
• Local mode = Used for alignment and testing.

UEM is the Universal Energy Management IC for DCT4 digital handportable phones. In
addition to energy management, it performs all the baseband mixed-signal functions.
Most of UEM pins have 2kV ESD protection. Those signals that are considered to be
exposed more easily to ESD have 8kV protection inside UEM. Such signals are all audio
signals, headset signals, BSI, Btemp, Fbus, and Mbus signals.
Regulators
UEM has six regulators for baseband power supplies and seven regulators for RF power
supplies. VR1 regulator has two outputs VR1a and VR1b.
Bypass capacitor (1uF) is required for each regulator output to ensure stability.

Reference voltages for regulators require external 1uF capacitors. Vref25RF is reference
voltage for VR2 regulator; Vref25BB is reference voltage for VANA, VFLASH1, VFLASH2,
VR1 regulators; Vref278 is reference voltage for VR3, VR4, VR5, VR6, VR7 regulators;
VrefRF01 is reference voltage for VIO, VCORE, VSIM regulators, and for RF.
The baseband is powered from five different UEM regulators:

Table 3: Regulator Descriptions (Continued)
Regulator Description
VIO Supplies both external and internal logic circuitries. This regulator is used by the LCD, flash, Bat-
man, Jupiter, GPS RF, GPS Baseband, and the UPP. The VIO regulator enters low Iq mode in sleep
mode.
VCORE Supplies the DSP, the core part of the UPP, and the GPS BB ASIC. The voltage is programmable
and the startup default is 1.35V. This regulator enters low Iq-mode in sleep mode.
VR1 (VR1A, VR1B) Uses two LDOs and a charge pump. VR1A is used in the UHF PLL, and VR1B is used
for Jupiter PLL.
VR2 Linear regulator used to supply the Jupiter RF ASIC.
VR3 Linear regulator used by the VCTCXO circuitry.
VR4 Linear regulator used by the UHF PLL and the UHF VCO.
VR5 Linear regulator used by the Batman and Alfred ASICs.
VR6 Linear regulator used by the Jupiter PLL.
VR7 Linear regulator used by the Batman ASIC.
RF Interface
In addition to the RF regulators mentioned, UEM handles the interface between the
baseband and the RF section. It provides A/D and D/A conversion of the in-phase and
quadrature receive and transmit signal paths, and also A/D and D/A conversions of
received and transmitted audio signals to and from the UI section. The UEM supplies the
analog AFC signal to the RF section according to the UPP DSP digital control. It also
converts PA temperature into real data for the DSP. The UPP controls the RFIC through
the 3-wire RFIC bus. UPP also provides PDM regulator for RF interface (RX/TX AGC
control).
Charging Control
The CHACON block of the UEM controls charging. Needed functions for charging controls
include: PWM-controlled battery charging switch, charger-monitoring circuitry, and
battery voltage monitoring circuitry. In addition, external components are needed for
EMC protection of the charger input to the baseband module. The DCT4 baseband is
designed to electrically support both DCT3 and DCT4 chargers.
Digital Interface
Data transmission between the UEM and the UPP is implemented using two serial
connections, DBUS (9.6 MHz) for DSP and CBUS (1.2 MHz in CDMA) for MCU. UEM is a
dual-voltage circuit: the digital parts are running from 1.8V and the analog parts are
running from 2.78V. Vbat (3.6V) voltage regulators inputs also are used.
Audio Codec
The baseband supports two external microphone inputs and one external earphone
output. The inputs can be taken from an internal microphone, from a headset
microphone, or from an external microphone signal source through a headset connector.

The output for the internal earpiece is a differential type output, and the differential
output is capable of driving 4Vpp to the earpiece with a 60 dB minimum signal to total
distortion ratio. Input and output signal source selection and gain control is performed
inside the UEM ASIC according to control messages from the UPP. Both a buzzer and an
external vibra alert control signals are generated by the UEM with separate PWM
outputs.
UI Drivers
The vibra, display LED, and keyboard LEDs are driven by open collector output drivers
inside UEM. These drivers can generate PWM square wave signals to these devices.
AD Converters
There is an 11-channel analog-to-digital converter in UEM. The AD converters are
calibrated in the production line.
