Stylish, Turnkey Solution Surpassing PC OEM Requirements
Conexant’s CX-9Z-NR0226 USB V.92 Dongle Modem design platform
consists of the CX93010-11Z USB Modem with 4th Generation SmartDAA®
and the CX20548-11Z SmartDAA 4 Line Side Device (LSD). The CX-9ZNR0226 is a full turnkey USB V.92 dongle modem styled to complement
today’s fashionable notebooks. The attractive sleek profile with soft rounded
curves is easily stored in the smallest of notebook cases. Conexant has
leveraged its extensive experience in working with PC manufacturers
and expertise in analog modem technology to develop a modem that will
withstand the demands of the toughest PC OEMs and surpass all categories
of standards testing for safety and Electromagnetic Compatibility (EMC).
Low Cost
The CX-9Z-NR0226 incorporates several cost-saving features. The CX9301011Z is offered in a small 20-pin Quad Flat No-Lead (QFN) package allowing
for the small yet cost efficient PCB. The CX20548 SmartDAA 4 LSD builds
on three generations of market leading silicon DAA devices. It reduces Bill
of Material (BOM) cost and necessary board space, making it the most
cost efficient silicon DAA in the market. It eliminates the need for costly
analog transformers, relays and opto-isolators typically used in discrete DAA
implementation for country-specific modem configurations. The result is
a worldwide reduced system cost solution using a single bill of materials.
The SmartDAA 4 is system-powered, making it the most reliable and best
performing silicon DAA in the market. The SmartDAA 4 is shipping in
every top PC OEM continuing Conexant’s long tradition of providing the
most Internet connections via analog modems than all of its competitors
combined.

Distinguishing Features
• Full turnkey design
• Elegant and stylish ID design
• Slim and compact
• Passes strict EMC and safety standards of the top PC OEMs
• Pre-certified for worldwide Telecom
Quick Time-to-Market
The CX-9Z-NR0226 is pre-tested for worldwide telecom compliance and can
be transferred to any board Original Design Manufacturer (ODM) for fast
time to market. The OEM can customize the design to their liking by adding
their own color scheme and logo. The design is fully controlled by Conexant
from the PCB to the USB cable and the ID designs to assure consistent
product quality.
The CX-9Z-NR0226 is a hardware modem using the CX93010-11Z and
CX20548-11Z chipset. Because it is a hardware modem, it can be easily
adopted in non-x86 CPU and non-Windows OS based systems. The modem
will operate with any system that has a USB CDC (Communication Device
Class) driver.
