PC Dial-Up Modems Controller-Based Modems USB V.92 Dongle Modem Platform CX-9Z-NR0226 Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for broadband communications and the digital home. Controller-Based Modem with SmartDAA® 4 for PC Applications Overall Measurements: 64 mm x 18 mm x 14 mm (length x width x height) 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. 4 mm x 4 mm 16-pin QFN 6 mm x 6 mm 20-pin QFN 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.
