Embedded Dial-Up Modems Controller-Based Modems CSM92/34/32 Serial Modem with 4th Generation SmartDAA CX93011 Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for communications and consumer applications. Controller-Based Modem with SmartDAA® 4 for Embedded Applications Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for broadband communications and the digital home. The CX93011 modem paired with the CX20548 SmartDAA® 4 Line Side Device (LSD), is ideal for embedded applications such as Point of Sale (POS) terminals, SetTop Boxes (STB), Video Recorders, Meters, Security Systems, Remote Site Management and other applications that require robust dial-up connectivity. The CX93011 serial modem device set consists of a CX93011 serial interface modem in a 6x6mm 20-pin Quad Flat-No Lead (QFN) package and CX20548 SmartDAA 4 LSD in a 4mmx4mm 16-pin QFN package. The device set integrates the microcontroller, digital signal processor, memory, and a worldwide DAA/telephone line interface function that operates with public switched telephone network (PSTN) telephone lines worldwide. The V.92 modem supports data modes up to 56 kbps and includes features such as Quick Connect, Modem-on-Hold, and PCM Upstream. A V.34 option and V.32bis option are also available. Conexant’s SmartDAA 4 line side device 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 countryspecific 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 CX93011 device set is pin-compatible with the CX90240 device set.
