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.
