The LSI Logic CBP3.0 chip is the most highly-integrated CDMA processing
solution available today for wireless handset designers. Thanks in large part to
the company's leading-edge G11
TM
CMOS process technology, which features
0.18-micron (Leff) gate length devices, system designers can pack more perfor-
mance and functionality into an ever-smaller footprint, supported by leading-
edge packaging capabilities. Phone manufacturers can use this integration to
reduce overall product size and power consumption while increasing reliability.
The CBP3.0 integrates voice codingincluding mixed-signal analog and digital
capabilitieswith a seamless interface to baseband modem, speaker, microphone
and IF/RF devices. The specific CDMA blocks include:
Two standard CDMA vocoders
Transmit digital-to-analog
(EVRC and QCELP13)
converter (DAC)
AMPS capability
Receive and transmit modems,
Receive filter
Phase-locked loops (PLL)
Transmit filter
Auxiliary DACs
Receive analog-to-digital
Voice codec
converter (ADC)
The chip also includes an on-chip ARM7TDMI
TM
control processor with
on-chip RAM, two OakDSPCore
digital signal processors (DSPs), DSP program
RAM/ROM, data RAM, digital logic for most modem functions, accelerators
and glue logic.

Low power consumption: Unique design
consumes less than 1mW during paging
and standby modes
Slotted-Paging Implementation:
Increases standby over conventional
implementations
Small size: The CBP at 16mm x 16mm
with 0.8mm pitch, featuring LSI Logic's
280-pin Chip Scale Package (CSP) mount-
ing technology is unmatched in its size-
to-performance ratio
Cost: Single chip integration of both
digital and mixed signal functions greatly
reduces manufacturing and material
costs, optimizing end-product value
Performance: The CDMA Baseband
Processor meets IS-95B requirements
including support for 64Kbps data rate
on the forward link
Time to Market: The CBP's powerful com-
bination of the ARM7TDMI processor and
dual OakDSPCore DSPs implementing
IS-95B functions lets product designers
focus on production issues rather than
CDMA integration

As with so many other SoC applications in the communications and networking
arena, LSI Logic's unique CoreWare
design methodology and library of building
blocks provides system designers with unsurpassed flexibility. CDMA cellular
and PCS vendors can take advantage of CoreWare technology to add value and
specific features to the single CDMA chip for dramatic product differentiation
all while accelerating time to market by shortening the product development
cycle and paving a smooth technology migration path into the future. Potential
value-added functionality may include a customized display interface; a DSP
dedicated to voice processing that can be used for voice recognition purposes;
and support for various Flash/RAM types, sizes, and speeds.
The single-chip integration helps reduce power consumption because the signals
pass between the on-chip functions blocks rather than between multiple chips at
the I/O drive level. Additionally, the single chip's digital circuitry operates at
only 1.8 volts, significantly reducing power consumption. Working in
conjunction with on-chip 3.3-volt mixed-signal circuitry (which includes a
phase-locked loop, voice codec, receive and transmit paths, and auxiliary ADC
and DAC units), the chip's digital 1.8-volt operation and sophisticated power-
saving capabilities pave the way for battery life increase.
