The CX93040 is Conexant's controller-based SmartModem with SPI host interface. It integrates a microcontroller, digital signal processor, memory and a SmartDAA® interface onto a single die. The modem comes in a small 20-pin Quad Flat-No Lead (QFN) package, adds support for SmartDAA 4 and adds Fax and SIA protocols, making it the most complete low-cost embedded modem in the market. The CX93040 is well suited to embedded applications such as Point of Sale (POS) terminals, Set Top Boxes (STB), Video Recorders, Meters, Security Systems, Remote Site Management, and other applications that require robust dial-up connectivity.
Conexant's SmartDAA 4 products allow customers to reduce their bill-of-material costs and PCB space requirements.
