Overview
QUALCOMM CDMA Technologies’ (QCT) MSM6500™ chipset solution
supports all major second generation (2G) and third generation (3G)
technologies deployed worldwide. It brings the rich experience of 3G
high-speed wireless data and worldwide roaming in a single-chip
offering. The MSM6500 supports data rates of up to 2.4 Mbps on third
generation (3G) CDMA networks that are ideal for high-end
entertainment and multimedia applications while allowing roaming with
second generation (2G) GSM/GPRS networks. The MSM6500 solution
supports CDMA2000
standards in a single-chip multimode implementation. The integration
of GSM and GPRS into the MSM6500 family represents a natural
evolution of QCT’s product line, building on the company’s extensive
CDMA expertise to develop multimode solutions that address a single
emerging worldwide market.
Like all the members of the MSM6xxx™ family, the MSM6500 solution
features QCT’s radioOne™ direct RF-to-baseband conversion
technology, resulting in cost-effective multi-band, multimode handsets
that can be produced in smaller form factors. The high-speed data
access of the MSM6500 chipset will enable a new generation of
handsets, smartphones, PDAs, video phones, data terminals,
handheld computers and other wireless devices offering advanced
video, gaming and multimedia services.
Seamlessly integrated into the MSM6500 solution is QCT’s
Launchpad™ applications suite, supported by our BREWapi™ (Binary
Runtime Environment for Wireless™ Application Programming
Interface), delivering superior multimedia, connectivity, position
location, user interface and storage functionality. The Launchpad suite
includes MPEG-4 video decoding/encoding, Qtunes™ MP3 audio
decoding, Compact Media Extensions™ (CMX™) MIDI-based
multimedia software, a digital camera interface, JPEG
encoder/decoder, USB host, Bluetooth™ connectivity capabilities
(which eliminates the need for wired connections between digital
devices), and gpsOne™ technology for highly accurate positioning.
The MSM6500 chipset solution consists of the MSM6500 baseband
processor, direct conversion RFL6000™ and RFR6000™ receiver
devices, the integrated direct conversion RTR6300™ transmit device
and GSM transceiver, the powerOne™ series PM6650™ power
management device and a compatible power amplifier device. It is also
compatible with the RFT6100™ if only CDMA2000 1X and 1xEV-DO
systems operation is desired. These devices perform all of the signal
processing and power management in the subscriber unit.
radioOne Technology
The radioOne solution offers a revolutionary technology for CDMA
transceivers that uses Zero Intermediate Frequency (ZIF), or direct
conversion, architecture for the wireless handset market. Direct
conversion eliminates the need for large IF Surface Acoustic Wave
(SAW) filters and additional IF circuitry, which reduces the handset Bill

of Materials (BOM), resulting in very cost-effective multi-band and
multimode handsets that can be produced in smaller form factors.
Using advanced techniques developed by QCT to enable high-
dynamic-range receivers, radioOne technology solves the problem of
stringent interference specifications with which CDMA phones must
comply. Our radioOne technology also incorporates the frequency
synthesis and passive elements used in converting baseband signals
to and from RF. A single external local oscillator is used for the CDMA
receiver, which provides the capabilities needed to operate on systems
around the world, and simplifies the procurement of parts while greatly
reducing the cost of designing CDMA handsets.
MSM6500 Device Description
advanced Java
In addition to the ARM core technology and radioOne architecture, the
MSM6500 chipset integrates two new QDSP4000™ digital signal
processor (DSP) cores, supports cost-effective high-performance
memory architecture, and offers other sophisticated features, including
an enhanced LCD interface, support for USB host controller through
an embedded USB On-The-Go (OTG) core, and a graphics
accelerator. The MSM6500 chipset utilizes a state-of-the-art 0.13u
CMOS production process and advanced packaging technology.
The MSM6500 solution integrates functions that support CDMA
operation and data rates of up to 2.4 Mbps on 1xEV-DO systems and
up to 307 kbps on forward and reverse links simultaneously on
CDMA2000 1X systems. These capabilities meet the Electronic
Industries Alliance/Telecommunications Industry Association (EIA/TIA)
IS-856 and Interim Standard 2000 (IS-2000) Revision A respectively.
The MSM6500 chipset is also fully backward compatible with
IS-95A/B cdmaOne™ networks. Receive diversity is supported on the
CDMA2000 1X and 1xEV-DO modes—enhancing voice capacity on
CDMA2000 1X systems and improving data throughputs on
CDMA2000 1X and 1xEV-DO systems. The MSM6500 GSM/GPRS
solution supports Phase 2+ of GSM and GPRS class B, multi-slot class
10 data services.
The MSM6500 chipset and system software supports QCT’s gpsOne
position location technology, which merges GPS satellite and network
information to provide a high-availability solution with industry-leading
accuracy and performance for a new class of mainstream CDMA2000 1xEV-
DO handsets. This solution not only meets the FCC E911 mandate under
the most challenging conditions, but also provides a ubiquitous platform for
a rapidly increasing number of location-based applications and services.
