Preliminary
AD6905
GENERAL DESCRIPTION
The AD6905 is an advanced, low-power baseband processing
solution from Analog Devices, and is part of the AD20msp500
SoftFone® chipset family. The AD6905 is intended for use in a
wide variety of feature-rich phones with TD-HSDPA / GSM /
GPRS / EGPRS system connectivity. It is designed to interface
easily to an application/OS processor, or to stand alone as a fully
integrated and easy-to-use solution for mobile handset and
wireless modem applications.
The processing speeds of the ARM9 and Blackfin DSP cores
enable advanced applications such as Streaming Audio and
Video services, various decoders supported by 3GPP such as
H.264, and H.263, and Multimedia services (MMS) and
Enhanced Message Service (EMS). Other supported audio
applications include various vocoders including FR, EFR, HR,
and AMR; software-generated polyphonic ringtones; and
advanced voice functions such as echo-cancellation, hands-free
(speakerphone) operation, intelligibility enhancement, and noise
reduction. Both core processors also support software-based
multimedia functions such as MP3 audio encoding and
playback, and MPEG4 video encoding and decoding. The
AD6905 includes interfaces for burst- and page-mode NOR
flash memories, SDRAM, PSRAM (cellular RAM), and NAND
flash memory. The AD6905 is able to boot directly from
NAND, offering the possibility to eliminate NOR flash from the
system altogether.
The Blackfin DSP is a high-performance, low-power, 16-bit
Digital Signal Processor (DSP) optimized for communications
and multimedia applications. The DSP is a resource for
implementing various signal processing functions in the
communications task such as speech processing, channel
equalization, and channel codec functions. Because of its
performance and programmability, this DSP architecture offers
increased flexibility in supporting audio and video processing
functions in software such as those used in MMS.
The AD6905 supports adaptive multi-rate speech codecs as well
as a full range of TD-SCDMA data services including circuit
switched and packet switched, up to 384kbps data class. The
processor also supports High-Speed Downlink Packet Access
(HSDPA) for data transfers as fast as 2.8Mbps. In addition, it
supports A5/1, A5/2, and A5/3—GEA1, GEA2, and GEA3—
encryption algorithms as well as operation in non-encrypted
mode. The highly programmable architecture and sophisticated
internal communication channels of the AD6905 offer
maximum flexibility to system designers. It can adapt to tighter
requirements led by changes in standards and multi-standard
handset implementation.
The AD6905 interfaces to all the peripheral subsystems of a
terminal, including the keypad, memories, display driver, USIM,
data interface and radio. It also has several general-purpose
interfaces that can be used to support additional handset options
such as multiple displays, Bluetooth modules, or cameras. The
AD6905 supports 16 external interrupts that are highly
programmable, enhancing the flexibility to interface with
external devices. The AD6905 interfaces to the AD6857
Advanced Audio/Baseband Codec and Power Management chip
through dedicated serial ports.
The AD6905 has a full-speed USB 2.0 On-The-Go (OTG)
interface. USB OTG provides low-cost connectivity for
consumer mobile devices such as cell phones, digital still
cameras, and MP3 players, allowing these devices to transfer
data via a point-to-point USB connection without a PC host.
The AD6905 also integrates a multimedia control module,
providing interface to external multimedia cards. These support
modules, along with the powerful processing capabilities of the
AD6905, allow extensive MMS (Multimedia Services)
applications to transfer data or programs from storage devices,
execute them on the baseband processor, and transmit them over
the wireless network. Such applications include MP3 playback,
processing of video clips, compression and decompression of
JPEG or MPEG4 images.
In addition to the MMS capability, the AD6905 allows mobile
phone users to connect to the Internet, download pictures and
ring tones to their phone and add EMS (Enhanced Message
Service) capability to their phone. EMS, an extension of the
SMS text messaging service, allows the user to send a
combination of simple melodies, pictures, sounds, animations,
modified text and standard text.
TEST AND DEBUG
The MCU JTAG interface, in conjunction with a 3rd party In-
Circuit Emulator (ICE), can be used for test and debug during
system integration. Through the Universal System Connector
(USC), and selected General Purpose I/O (GPIO) pins. DSP
emulation can be performed using Analog Devices’ in-circuit
emulation tools, which are part of the CROSSCORE
Development and Debug Tools Suite. The CROSSCORE
components include the VisualDSP++™ software development
environment, EZ-KIT Lite™ evaluation systems, and emulators
for rapid on-chip debugging. In addition to the DSP
development tools suite, ADI offers a superset of the
development tools for the baseband system, called
VisualFone™. The VisualFone Evaluation and Development
Environment provides the capabilities needed to evaluate,
develop, test, and debug mobile terminals based on the AD6905
baseband processor.
