and boost average data throughput. Non-error-correcting mode
is also supported.
Fax Group 3 send and receive rates are supported up to 14.4 KBps
with T.30 protocol. V.80 synchronous access mode supports host-
controlled communication protocols, e.g., H.324 video conferencing.
Audio recording and playback over the telephone line interface
using A-Law, µ-Law, or linear coding at 8 KHz sample rate supports
applications such as remote digital TAM.
SmartMC II™/SmartAMC™ and AC-Link
Modem Device Sets
Conexant Offers a Family of AC-Link Modem
and Audio/Modem Devices to Support Mobile
and Desktop PC Applications
Conexant’s SmartMC II™ and SmartAMC™ system solutions provide
the lowest system costs, improved time-to-market and enhanced
features and performance. The product family includes all the
necessary hardware and software (algorithms and drivers) required
to support modem-only or audio/modem solutions. The Conexant
AC-Link system solutions support a wide range of architectures
including MDC card or Mini PCI designs using the Conexant
RipTide
TM
digital controllers, and motherboard designs using either
the Conexant RipTide
TM
digital controllers or core logic solutions
incorporating digital audio and modem support.
Motherboard designs include desktop solutions using the Advanced
Communications Riser (ACR), Audio Modem Riser (AMR) or
Communications Network Riser (CNR) connectors, and notebook
designs using the Mobile Daughter Card (MDC) or Mini PCI
connector, or custom form factors. Conexant played an important
role in the definition of the AMR and MDC specifications and has
helped define the majority of core logic solutions introduced
on the market.
Motherboard configurations using the ACR, AMR, CNR, MDC or
Mini PCI architectures simplify the modem homologation process
by allowing the card to be certified independent of the actual
system motherboard design. These architectures also support the
ability to remove all analog circuitry from the motherboard, lead-
ing to higher-quality audio and reduced motherboard complexity.
The SmartMC II and SmartAMC system solutions meet the PC 99
System Design Guide specifications, offering significant benefits
such as better overall system performance and standards based
power-management support.
These solutions provide all the features of Conexant’s industry-
leading SoftK56 software modem. The communications control
code for the SmartMC II and SmartAMC are also equivalent to
other Conexant modem products. This common control code
allows OEMs that have already tested the HSF modem with
their standard applications to move quickly into production with
the SmartMC II and SmartAMC. In addition to standard modem
features, all three chipsets offer Caller ID, enabling users to
identify the source of incoming calls. The chipsets also feature
Wake-On-Ring functionality, allowing PCs in a low-power,
suspended state to automatically turn back on after receiving a
phone call. This unique feature enables PCs to receive incoming
messages that they would otherwise miss. Conexant’s modem
CODEC fully supports Intel’s AC 97 version 2.1 specification,
designed to help PC manufacturers adopt new modem technologies
more quickly and cost-effectively. Conexant collaborated with Intel
to develop this specification, and contributed key modem technology.
Because the modems are software based, they can be upgraded
for value-added features such as standards, simply by downloading
the appropriate drivers.
SmartMC II Modem Device Set
The SmartMC II modem CODEC device set supports analog data
communications at up to 56 KBps, analog fax at 14.4 KBps, and
voice/remote TAM. SmartMC II also supports AC-Link (AV 97)
operation for ACR, AMR and CNR interface and MDC and Mini
PCI applications. Enhanced features, such as monitoring of local
extension status without going off-hook, are also supported.
The device set consists of a Host Side Device (HSD) in a 48-pin
TQFP, and a LSD in a 32-pin TQFP.
SmartAMC Modem Device Set
Conexant’s SmartAMC audio modem CODEC device supports
analog data at up to 56 KBps, analog fax at 14.4 KBps,
voice/remote TAM functionality, and a 90dB SNR.
SmartAMC also enables AC-Link operation for ACR, AMR and CNR
interfaces, and MDC or Mini PCI applications. The SmartAMC also
supports the following enhanced features: Monitoring of local
extension status without going off-hook; voice/remote TAM; HRTF;
A3D; EAX 1.0/2.0; Conexant Player; enhanced speakerphone;
and voice over games. The device set consists of a HSD in a
48-pin TQFP, and a line side device LSD in a 32-pin TQFP.
