1 INTRODUCTION / OVERVIEW
1.1 QSC6055 Chipset
The QSC60x5 family of devices represents the next generation of chipset architecture and
enhancements for the QCT value and multimedia tiers of products. The QSC60x5 family
includes the QSC6055 and QSC6065 devices (supporting CDMA2000 1x voice and data,
and Simultaneous-GPS (S-GPS)), the QSC6075 device (adding CDMA2000 EV-DO rel. 0
support) and the QSC6085 device (adding CDMA2000 EV-DO rev. A support). These
airlink and multimedia capabilities are supported by integrating Mobile Station Modem™
(MSM™) baseband, radioOne® RF, and power management functionality into a single 12
mm x 12 mm chip scale package (CSP). Together these functions perform all the signal
processing and power management tasks within a subscriber unit. This enables reduced
handset complexity, cost, time-to-market, and board-space requirements while providing
many features and functionalities.
The global expansion of 3G CDMA 1x networks has extended the availability of
high-speed, wireless data access. With increased accessibility comes increased demand for
wireless devices that function as cameras, camcorders, personal video players, MP3 audio
players, gaming consoles, and phones. To efficiently support next-generation data speeds
and functionality, wireless devices must integrate applications processors with
high-performance modems. The QSC60x5 devices extend the level of integration to
include radio frequency and power management functions.
3G products based upon the QSC60x5 devices may include:
■ Voice and data phones
■ Music player-enabled devices and applications
■ Camera phones
■ Multimedia phones, including gaming, streaming video, videoconferencing, and more
■ Position location devices
■ Other applications and devices
QSC60x5 benefits are applied to each of these product-types, including:
■ Higher integration to reduce PCB surface area, power consumption, time-to-market,
and BOM costs while adding capabilities and processing power
❒ Baseband functions, including multiple hardware cores
❒ radioOne RF and analog functions (Rx and Tx, both eliminating their intermediate
frequency (IF) components)
❒ Power management functions
■ Integrated hardware cores eliminate multimedia co-processors, providing superior
image quality and resolution for mobile devices while extending application times:
❒ Longer run-time for mobile devices over other industry solutions that use
companion processors
■ Location-based services and applications, including points of interest, personal
navigation, and friend finder
■ Single platform that provides dedicated support for all market leading CODECs and
other multimedia formats to support carrier deployments around the world
