MSM6250 Chipset Architecture Using QCT’s radioOne Zero Intermediate Frequency (ZIF)

Overview

The MSM6250 chipset also supports the Binary Runtime Environment

for Wireless™ (BREW™) platforms. With BREW routines, protocols

and tools, handset manufacturers and developers can develop

embedded wireless applications and BREW-based products more

quickly and easily.

A complete system solution that operates on all GSM, GPRS and

UMTS networks worldwide, QCT's MSM6250™ Mobile Station

Modem™ (MSM™) chipset and system software offers a rich feature

set of multimedia data applications and supports state-of-the-art

position location capabilities. The MSM6250 device supports

streaming video, audio, still-image and video encoding and decoding,

2D and 3D graphics acceleration, and Java^®acceleration. It also

integrates a megapixel camera interface, complete Bluetooth™

baseband support, and gpsOne™ position location technology.

The MSM6250 device integrates the ARM926EJ-S processor, offering the

ARM® Jazelle™ Java™ hardware accelerator, two low-power, high-

performance QDSP4000™ Digital Signal Processor (DSP) cores and a

wide-band stereo codec for support of enhanced digital audio applications.

The QDSP4000 core eliminates the need for the multimedia companion

processors normally required for video and audio-based applications,

playing MP3 music files, MIDI synthesizer, video and still-image record and

playback, and 2D/3D graphics functions. By removing the need for costly

application co-processors and memory subsystems, the MSM6250 solution

reduces bill-of-materials (BOM) costs and increases standby and talk times.

The MSM6250 is a member of QCT's MSM6xxx™ family of 3G

chipsets that offer more powerful processors, high-quality video, audio

and graphics technologies and high-speed data connectivity. The

MSM6250 solution delivers superior performance while reducing

complexity, cost and board-space requirements.

MSM6250^™CHIPSET SOLUTION

Combine these features with QCT's radioOne™ Zero Intermediate

Frequency (ZIF) direct conversion architecture - which eliminates

the need for large IF Surface Acoustic Wave (SAW) filters and

additional IF circuitry - and you have a system solution that

enables the development of cost-effective multi-band, multimode

handsets offering superior talk and standby times in smaller form

factors.

radioOne Technology

MSM chipsets using radioOne technology offer the benefits of direct

conversion no matter what air interface is being used: CDMA, GSM,

GPRS or UMTS. Using advanced techniques developed by QCT to

enable high-dynamic-range receivers, radioOne ZIF technology solves

the problem of stringent interference specifications with which CDMA

phones must comply. The radioOne technology also incorporates the

frequency synthesis and passive elements used in converting baseband

signals to and from RF. For the UMTS receiver, a single external local

oscillator is used, 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 UMTS handsets.

The MSM6250 system solution supports data rates of up to 384

kbps, providing manufacturers worldwide with the ability to

develop consumer products that offer voice, position location

technologies, high-speed data, and video over wireless networks.

Network operators will also benefit from the cost efficiencies and

rapid time-to-market that the solution delivers for next-generation

services.

gpsOne Technology

By integrating the gpsOne baseband functionality, the MSM6250 chipset

provides an Assisted-GPS (A-GPS) solution with unmatched acquisition

speed, accuracy and sensitivity for services on GSM/GPRS/UMTS networks

worldwide. This integrated solution addresses the rapidly expanding market

for location-based services and will enable handset manufacturers to

develop products to support a wide variety of applications with three

standards-approved modes of operation: Mobile-Assisted, Mobile-Based

and Standalone GPS.

From circuit-switched high-end voice to packet-switched high-

speed data, from audio to images and video, the MSM6250

system solution supports a wide range of consumer products

offering a variety of capabilities, including Personal Digital

Assistant (PDA) and Internet applications such as e-mail, e-

commerce, multimedia file transfer, video streaming, picture

messaging, Web access and more.

The gpsOne capability enabled by the MSM6250 chipset can be accessed

via QUALCOMM's Launchpad™ suite. The gpsOne API component of the

Launchpad suite provides applications with easy access to location

information and control over their operation. The MSM6250 chip leverages

SnapTrack®'s proven A-GPS algorithms for multipath mitigation, power

reduction, sensitivity enhancement and minimized wireless bandwidth

utilization. These leading-edge algorithms, combined with the high level of

integration, provide unmatched GPS acquisition speed, accuracy and

sensitivity, while minimizing handset cost, space requirements and battery

usage, and reducing communications bandwidth.

The MSM6250 system solution consists of the MSM6250

baseband processor, direct conversion RFL6200™ and

RFR6200™ receive devices, the direct conversion RTR6250™

GSM transceiver and UMTS transmit device, powerOne™ series

PM6650™ power management device, a compatible power

amplifier device, a complete UMTS/GSM/GPRS protocol stack and

multimedia system software. These devices, plus the system

software, perform all of the signal processing and power

management in the subscriber unit.

MSM6250^™CHIPSET SOLUTION

RFL6200 Device Description

RFR6200 Device Description

Integrated into the RFL6200 device are low-

noise amplifiers (LNAs) for the UMTS

bands, with three gain settings that are

programmable through the serial bus

interface (SBI).

The RFR6200 device is the radioOne zero IF

downconverter. The device has a mixer which,

when combined with the RFL6200, provides full

RF-to-baseband downconversion for UMTS

bands. The LO generation for direct conversion is

integrated on-chip.

Operating modes — sleep, Receive (Rx), and Rx/Transmit (Tx)

— as well as LNA bias currents are all automatically adjusted

via software in order to minimize DC power consumption.

Depending on handset status, the LNA bias current adjusts

accordingly to meet RF performance requirements with

minimal power consumption.

Increase in standby time is achieved by selective circuit power down,

gain control and bias current. These features, along with all of the

radioOne chipset functions, are controlled by the MSM6250 chipset.

The device is designed to operate with 2.7 to 3.1 V power supplies

and is compatible with single-cell Li-Ion batteries.

The device is fabricated using SiGe BiCMOS process, which is

suited for high performance RF circuits. The RFL6200 is

packaged in a very small 16-pin bump chip carrier (16

BCCP).
