and the CX20548
SmartDAA 4 LSD. The
CX-9Z-NR0226 is a full
turnkey USB V.92 dongle
modem that is styled to complement today's fashionable
notebooks and other embedded platforms with an
available USB port. 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 its
expertise in analog modem technology to develop a
modem that withstands the demands of the toughest PC
OEMs, and surpass all categories of standards testing
for safety and EMC.
Overall Measurements:
64 mm x 18 mm x 14 mm
(length x width x height)
4 mm x 4 mm
16-pin QFN
6 mm x 6 mm 20-pin QFN
Low Cost
The CX-9Z-NR0226 incorporates several cost-saving
features. The CX93010 is offered in a small 20-pin QFN
package that allows for the small, yet cost efficient PCB.
The CX20548 SmartDAA® 4 LSD builds on four
generations of market leading silicon DAA devices and
reduces the BOM cost and necessary board space,
making it the most cost efficient silicon DAA in the
market. The CX20548 SmartDAA 4 LSD eliminates the
need for costly analog transformers, relays, and optoisolators that are typically used in discrete DAA
implementation for country-specific modem
configurations. The result is a worldwide reduced
system cost solution using a single BOM. The
SmartDAA 4 is system-powered, making it the most
reliable and best performing silicon DAA in the market.
Conexant has shipped several hundreds of millions
SmartDAA 4 LSDs worldwide, continuing its long
tradition of providing the most Internet connections
using analog modems than all of its competitors
combined.
