Nokia Customer Care Technical Summary
Baseband Module Overview
The mobile terminal uses a CDMA single mode engine (Cellular/ 800) with
Qualcomm baseband consisting of two ASICs:
z Qualcomm Single Chip 6010
z 64Mb Flash memory with 16Mb of Psram memory
QSC6010
TM
The QSC6010 device represents QCT’s next generation of chipset architecture
and enhancements for voice and entry-level multimedia handsets by integrating
Mobile Station Modem™ (MSM™) baseband, radioOne RF, and power
management functionality into a single 15 mm x 15 mm mini scale package (MSP).
Together these functions perform all of the signal processing and power
management tasks within a subscriber unit. This enables reduced handset
TM
complexity, cost, time to market, and board-space requirements while providing
many features and functionalities.
The QSC6010
TM
device integrates a mixed-signal baseband chip that enables
manufacturers to meet or exceed the specifications of mobile stations for
worldwide cdmaOne and 3G CDMA systems, including IS-95-A, IS-95-B, IS-2000
1x Release 0.
Subsystems within the QSC6010
TM
device include a CDMA processor, a DFM
processor, QCT’s QDSP4000™ DSP for voice compression, PLL and an ARM®
ARM926EJ-S™ microprocessor. Also integrated in the QSC6010
TM
device are an
audio voice codec and analog interfaces for the radioOne RF ASICs. Controllers
for an R-UIM, GPIOs, and peripheral interfaces complete the system integration.
The QSC6010
TM
device integrates all low-cost wireless handset power
management, general housekeeping, and user interface support functions into a
single mixed signal IC. Its versatile design is suitable for low-cost CDMA handsets.
The power management portion accepts power from common sources – battery,
external charger or adapter – and generates all the regulated voltages needed to
power the appropriate handset electronics. It monitors and controls the power
sources, detecting which sources are applied, verifying that they are within
acceptable operational limits, and coordinates battery recharging while maintaining
the handset electronics supply voltages. On-chip voltage regulators generate nine

Technical Summary
programmable output voltages using low dropout voltage regulators, all derived
from a common trimmed voltage reference.
Flash Memory
The Simultaneous Read/Write architecture provides simultaneous operation by
dividing the memory space into 4 banks, which can be considered to be four
separate memory arrays. The device can improve overall system performance by
allowing a host system to program or erase in one bank, then immediately and
simultaneously read from another bank with zero latency.
This device requires a single 3.0 volt power supply for both read and write functions.
Its command set is entirely compatible with the JEDEC single-power-supply Flash
standard.

Nokia Customer Care Technical Summary
RF Module Overview
The RF module receives and demodulates the radio frequency signals from the
base station and transmits the modulated RF signals to the base station. It
communicates between QSC6010 , PA and Antenna.
Transmitter
The transmitter module is a baseband -to- RF module, an integral component of
QUALCOMM’s QSC6010 chipset. All radioOne ICs are highly integrated and fulfill
CDMA2000 standard. Overall radioOne performance depends on the combined,
complementary performance of all the ICs in the chipset.
The transmitter module in the QSC6010 provides the Zero-IF transmit signal path
for Cellular-CDMA transmission. For this module, Cellular-CDMA refers to band
classes 0 as defined by the cdma2000 standard, with mobile station transmitters
operating between 824 and 849 MHz. The transmit signal path includes baseband
amplifiers, quadrature upconversion, gain control RF amplification, and an output
driver amplifier.
Receiver
The receiver module is an RF-to-baseband module, an integral component of
QUALCOMM’s QSC6010 chipset. All radioOne ICs are highly integrated and fulfill
CDMA2000 standard. Overall radioOne performance depends on the combined,
complementary performance of all the ICs in the chipset.
The receiver module in the QSC6010 provides the Zero-IF receiver signal path for
Cellular-CDMA reception. For this module, Cellular-CDMA refers to band classes 0
as defined by the cdma2000 standard, with mobile station receivers operating
between 869 and 894 MHz. The Rx signal path includes the LNA, quadrature
downconversion, and baseband functions.
