MSM6100™CHIPSET SOLUTION
ENABLING THE FUTURE OF COMMUNICATIONSTM
radioOne technology
The radioOne solution offers a revolutionary technology for CDMA
transceivers that uses 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 BOM, facilitating 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. 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 will provide the capabilities needed to operate
on systems around the world and will simplify the procurement of
parts and greatly reduce the cost of designing CDMA handsets.
MSM6100 Device Description
The 3G CDMA2000 1X MSM6100 chipset and
system software features radioOne direct
conversion architecture and incorporates a low-
power, high-performance reduced instruction set
computing (RISC) microprocessor core featuring
the ARM926EJ-S™ central processing unit
(CPU) and Jazelle™ accelerator circuit for advanced Java®
applications from ARM®Limited.
Compliant with the Electronic Industries Alliance/Telecommunications
Industry Association (EIA/TIA) Interim Standard 2000 (IS-2000)
Revision A, the MSM6100 chipset and system software incorporates
the advanced feature set of QCT’s Launchpad suite of technologies,
integrated Moving Picture Experts Group (MPEG-4) video
decoding/encoding, MPEG Layer-3 (MP3) audio decoding, a 2D/3D
graphics accelerator for advanced gaming applications, a Compact
Media Extension™ (CMX™)/Musical Instrument Digital Interface
(MIDI) synthesizer, a digital camera interface, an enhanced liquid
crystal display (LCD) interface, and Joint Photographic Experts
Group (JPEG) encoding/decoding.
The MSM6100 solution also integrates two low-power, high-performance
QDSP4000™ digital signal processor (DSP) cores and supports cost-
effective memory architectures. Use of the ARM926EJ-S™ CPU and
QDSP4000 DSP eliminates the need for the multimedia companion
processor(s) normally required for video-based applications, playing
MP3 music files and MIDI synthesizer/CMX functions.
The MSM6100 solution supports QUALCOMM’s gpsOne™ position
location technology, including standalone mode in which the
handset can act as a GPS receiver. The gpsOne solution, featuring
SnapTrack® technology, offers robust data availability under the
most challenging conditions, whether in concrete-and-steel high-
rises, convention centers, shopping malls, or urban canyons. Using
a hybrid approach that utilizes signals from both the GPS satellite
constellation and from CDMA cell sites, the gpsOne solution
enhances location services availability, accelerates the location
determination process and provides better accuracy for callers,
whether during emergency situations or while using GPS-enabled
commercial applications. The MSM6100 solution also supports the
Launchpad’s VectorOne™ compass capability.
