ETC CX81210-31

LAN/Soft V.92 Modem
Combo with Integrated
Physical Layer Device
Set for PCI/Mini PCI
CX81210 Network Controller and CX20493 SmartDAAä 3 Line Side
Device
Overview
Features
The Conexantä low-cost LAN/Soft V.92 Combo Device set with Conexant’s
integrated physical layer technology and third generation SmartDAAä technology
(SmartDAA 3) supports 10/100 Ethernet networking and host-processed V.92
analog data modem with V.44 data compression/14.4 kbps fax modem operation.
By combining the MAC, PHY and modem system side device into one device, this
device set constitutes the most compact, lowest cost Ethernet/soft V.92 chipset in
existence. Only two chips are needed to accomplish the level of communication
functionality that previously took three or even four devices. This device set is ideal
for applications in the notebook, “broadband ready” consumer desktop, and SOHO
desktop PC markets requiring a low-cost, flexible LAN/modem communications
solution.
General Features
This device set consists of a CX81210 Network Controller with Integrated Physical
Layer device in a 208-ball fine pitch ball grid array (FPBGA) and a CX20493
SmartDAA 3 Line Side Device (LSD) in a 28-pin quad flat no-lead (QFN) package.
(Table 1). A simplified device set interface is illustrated in Figure 1.
The CX81210 Network Controller contains an integrated PHY device, provides a
direct PCI bus connection to the host processor, and connects to the Conexant
CX20493 SmartDAA 3 device through the OEM-supplied DIB for connecting to the
PSTN/GSTN telephone line in the U.S./Japan/Canada and worldwide.
The CX81210 Network Controller integrates internal circuits into a single VLSI (very
large scale integration) die. Internal circuits include clock, ARM7 processor, PCI
Bus interface logic, control and status registers, ROM, RAM, IEEE 802.3-compliant
Media Access Control (MAC), MII, IEEE 802.3-compliant PHY Transceiver,
SmartDAA 3 system side device (SSD), general purpose input/output registers, and
internal ringwake filter.

(Continued on Page 3)
Modem data pump and controller functions are processed in a Pentium MMXcompatible PC using host-signal processing modem software (i.e., soft modem).
In ITU-T V.92/V.90/K56flex data mode, the modem can receive data at speeds up to
56 kbps from a digitally connected V.92/V.90 or K56flex-compatible central site
modem. A V.92/V.90/K56flex modem takes advantage of the PSTN which is
primarily digital except for the client modem to central office local loop and are ideal
for applications such as remote access to an Internet Service Provider (ISP), on-line
service, or corporate site. In this mode, the modem can transmit data at speeds up
to 48 kbps in V.92 mode or up to V.34 rates in V.90 mode.

LAN/Soft V.92 Data/Fax Modem Combo with Integrated Physical Layer Device Set Product Summary

Overview (Continued)
In V.34 data mode, the modem operates at line speeds up to
33.6 kbps.
Data compression (V.44/V.42 bis/MNP 5) and error
correction (V.42/MNP 2-4) modes are supported to
maximize data throughput and data transfer integrity. V.44 is
a more efficient data compression than V.42 bis that
significantly increases downstream throughput thus reducing
the download time for the types of files associated with
Internet use, such as Web pages and uncompressed data
such as in graphics, image, audio, and document files. V.44
data compression can achieve compression rates of more
than 25% over V.42bis. Typical compression ratio for V.44
on Web type data is approximately 6-1 resulting in overall
effective data throughput rate up to 300 kbps for a 56-kbps
connection. Non-error-correcting mode is also supported.
Conexant's SmartDAA 3 technology also offers the following
advantages over discrete and other silicon DAAs:
•
•
•
•
•
•
•
Incorporating Conexant’s proprietary DIB design (patent
pending) and other innovative DAA features, the
SmartDAA 3 architecture simplifies application design,
minimizes layout area, and reduces component cost for
worldwide support.
The SmartDAA 3 architecture eliminates the need for a
costly line transformer, relays, and opto-isolators
typically used in discrete DAA (Data Access
Arrangement) implementations. Product
implementation is also simplified by eliminating the
need for country-specific board configurations enabling
worldwide homologation of a single modem board
design.
The SmartDAA 3 system-side-powered DAA operates
reliably without drawing power from the line and
operates on long loops and poor line conditions.
The SmartDAA 3 uses a fully differential digital interface
which provides robust performance in the presence of
common mode noise.
Many SmartDAA 3 functions are software configurable
providing a flexible solution to often changing
worldwide regulations.
Enhanced features, such as monitoring of local
extension status without going off-hook, are also
supported.
For over a decade, Conexant has assisted customers
with DAA technology and homologation. This expertise
and system level approach has been leveraged in this
product.

Remote audio recording and remote audio playback
over the telephone line interface is supported using ALaw, µ-Law, or linear coding at 8000 Hz sample rate to
support applications such as digital telephone
answering machine (TAM) and voice annotation.
Fax Group 3 send and receive rates are supported up to
14.4 kbps with T.30 protocol.
V.80 synchronous access mode supports hostcontrolled communication protocols, e. g., H.324 video
conferencing.
Mini-PCI and PCI reference design kits are available to
minimize application design time and costs.
