The Conexant CX81801 modem is ideal for embedded applications such as POS Terminals, Set-Top Boxes, Video Recorders, Metering, Security, Remote Site Management and any other application that requires robust dial-up connectivity. The device set integrates the micro controller, digital signal processor, memory and a worldwide DAA/telephone line interface function that operates with PSTN telephone lines worldwide. The CX81801 modem supports data/fax/Telephone Answering Machine (TAM) with up to 56 kbps analog data and 14.4 kbps fax modem operation. The V.92 modem includes V.92 features such as Quick Connect, Modem-on-Hold™ and PCM Upstream. The modem device is also available in V.34 and V.32bis options. The CX81801 modem device set consists of a CX81801 modem in either a 128-pin TQFP or 28-pin CTLGA package, and a Line Side Device (LSD). The CX81801 128-pin TQFP supports either the SmartDAA 3 LSD (CX20493 28-pin QFN) or the SmartDAA (CX20463 32-pin TQFP). The SmartDAA 3 requires fewer discrete components for a low-cost solution. The CX81801 128-pin TQFP supports serial and parallel interface and optional full-duplex speakerphone. The CX81801 Modem in a 28-pin CTLGA supports SmartDAA 3 LSD (CX20493 28-pin QFN). This device targets applications that require the smallest possible dimensions. The CTLGA package has the same footprint as a TSSOP package. The CX81801 28-pin CTLGA supports a serial interface. |
