MSM6000 CHIPSET SOLUTION

MSM6000 CHIPSET

At QUALCOMM CDMA

Technologies (QCT), we strive

to constantly improve the

indispensable communication

tools we all use every day. QCT

creates state-of-the-art chipsets,

system software, development

tools and products – such as

the Wireless Internet

Launchpad™ suite of

technologies and software –

that support the most advanced

digital wireless features and

functionality available for

wireless devices and base

stations – while continually

reducing complexity, cost and

board-space requirements.

The MSM6000™ solution,

part of QCT’s MSM6xxx Mobile

Station Modem (MSM™) family

of chipsets and system software,

uses QCT’s revolutionary

radioOne™ Zero Intermediate

Frequency (ZIF), or direct

conversion, architecture and

supports Release 0 of the

CDMA2000 1X standard. The

MSM6000 chipset, including

the radioOne RF components,

reduces the total number of

radio components by half,

shortens handset development

and test times and enables

higher handset production

yields. These features contribute

to reducing overall handset

design and manufacturing costs

as well as shortening time-to-

market.

The MSM6000 chipset

solution consists of the

MSM6000 baseband processor,

direct conversion RFL6000 and

RFR6000 receive devices, direct

conversion RFT6100 transmit

device, PM6000 power

management device and a

compatible power amplifier

device. These devices perform

all of the signal processing and

power management in the

subscriber unit.

MSM6000TTMM

MSM6000 DEVICE DESCRIPTION

The MSM6000 CDMA2000 1X

solution is fully backward

compatible with IS-95A/B, and

is optimized to support voice

and basic data capabilities.

While providing CDMA2000

network benefits, it enables a

seamless migration path to 3G

services and applications, and

improved voice capacity in the

CDMA2000 network.

An entry-priced solution, the

MSM6000 device reduces radio

bill-of-materials (BOM) costs

and improves handset standby

and talk times over current

solutions.

The MSM6000 device

interfaces directly with QCT’s

new radioOne RF ASICs.

Subsystems within the

MSM6000 device include a

CDMA processor, a DFM

processor, QCT’s QDSP2000™

DSP for voice coding, PLL and

an ARM7TDMI®

microprocessor. Also integrated

in the MSM6000 device are an

audio voice codec and analog

interfaces for the radioOne RF

ASICs. Controllers for an R-UIM

(CDMA SIM), GPIOs, and

peripheral interfaces complete

the system integration.

The MSM6000 solution

supports two-way Short

Messaging Service (SMS) and

data rates of up to 14.4 kilobits

per second (kbps), and is

compliant with IS-2000 Release

0, which addresses key attributes

of network voice capacity

improvements and significantly

extended handset standby times.

The MSM6000 device is offered

in a 208-ball Fine-Pitch Ball

Grid Array (FBGA) production .

QCT provides a complete

software suite, Dual-Mode

Subscriber software™ (DMSS™),

for building handsets around the

MSM6000 chipset. DMSS

software is designed to run on a

Subscriber Unit Reference™

(SURF™) phone platform, an

optional development plat-form

optimized to assist in evaluating,

testing and debugging DMSS

software.

radioOne is a revolutionary

technology for CDMA

transceivers that uses Zero

Intermediate Frequency (ZIF), or

direct conversion, architecture for

the wireless handset market. This

direct conversion eliminates the

need for large IF Surface

Acoustic Wave (SAW) filters and

additional IF circuitry, which

reduces the handset BOM,

resulting in cost-effective

multiband and multimode

handsets that can be produced in

smaller form factors.

Using advanced techniques

developed by QCT to enable

high-dynamic-range receivers,

radioOne 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.

MSM6000 CHIPSET SOLUTION

Integrated into the RFL6000

device are two Low Noise

Amplifiers (LNA): a Cellular LNA

and PCS LNA. Both LNAs utilize

three gain settings that are

programmable through the

Serial Bus Interface (SBI)

Operating modes—Sleep, Rx,

and Rx/Tx, as well as LNA bias

currents, are all automatically

adjusted via software to minimize

DC power consumption.

Depending on handset status,

the LNA bias current adjusts

automatically to meet RF

performance requirements with

minimal power consumption.

The device is fabricated using

a SiGe BiCMOS process, which

is suited for high performance RF

circuits. The RFL6000 device is

packaged in a very small 16-pin

bump chip carrier (16-pin

BCC++).

The RFR6000 device is the

radioOne zero IF down

converter. The device has 3

mixers which, when combined

with the RFL6000 device,

provide full RF-to-baseband

down conversion for the cellular,

PCS, and GPS band. The LO

generation block produces all

LO signals so that only one

external single band VCO is

required for all CDMA frequency

bands of operation.

Included on chip is the GPS

LNA as well as the entire GPS

VCO including resonant

components. The Rx PLL, which

resides on the transmit

companion IC, the RFT6100

device, is switched between the

GPS VCO and the external Rx

VCO.

Extension of standby time is

achieved by selective circuit

power down, gain control, and

bias current. These features

along with all of radioOne

chipset functionalities are

controlled by QUALCOMM’s

MSM (Mobile Station Modem).

The device is designed to

operate with 2.7-to-3.1volt

power supplies and is

compatible with single-cell Li-Ion

batteries. Compatibility to the

lower voltage (1.8 to 3.1 volts)

is assured when the VDDM is

connected to the MSM pad

voltage.

The RFR6000 device is

fabricated using a SiGe

BiCMOS process, which provide

high frequency, high-precision

analog circuits as well as low-

power CMOS functions.

Package type is a 40-pin

BCC++, which includes a large

ground slug for improved

grounding, mechanical strength,

and thermal conductivity.

RFR6000 DEVICE DESCRIPTION

MSM6000 CHIPSET SOLUTION

QUALCOMM CDMA TECHNOLOGIES

The RFT6100 is a direct

conversion IC that integrates all

the up-conversion and

modulation functionality

necessary for CDMA and FM

mode phones operating in

Cellular and PCS bands. This

transmit chip consists of I/Q

modulators, one for Cellular and

the other for the PCS band. The

baseband I/Q input from the

MSM directly modulates the

Cellular or PCS carrier derived

from the respective LO

generation circuit.

Both the Cellular and PCS

output drive their own variable

gain amplifier (VGA) with a gain

control range of 85 dB. A final

Cellular driver amplifier provides

a modulated RF output. To

accommodate split band and

filtering, the PCS VGA drives two

output amplifiers that can be

selected independently or

simultaneously via an input

selectable switch. All RF outputs

have fully integrated 50-ohm

matching networks.

Integrated on the RFT6100 is

the receiver PLL, the transmit PLL,

and the entire transmit VCO

including resonant components.

The VCO drives the LO

generation block which in turn

generates the required Local

Oscillator signal for all CDMA

bands of operation.

thereby reducing component

count, space, cost.
