Host-Processed, V.90/K56flex Modem Device Set with CX11250 Host Side Device, CX20463 SmartDAA, and Optional CX20437 Voice Codec for PCI Bus/Mini PCI Based Mobile Applications
INTRODUCTION OVERVIEW The Conexant SmartHSF Host-Processed (SoftK56) V.90/K56flex Modem Device Family with SmartDAA technology supports analog data up to 56 kbps, analog fax to 14.4 kbps, telephone answering machine (TAM), and PCI Bus/Mini PCI host interface operation. In addition, the device set optionally supports cellular phone interface (PDC high speed/PDC packet data, PHS data, CDMA/CDMA Packet data, GSM data) or voice/speakerphone. These modem devices meet the size and power requirements of the mobile environment. Table 1-1 lists the available models. The modem operates with PSTN telephone lines in the U.S./Japan/Canada and, optionally, worldwide. Optional cellular interface supports Japanese PDC (Personal Digital Cellular) and PHS (Personal Handyphone System) phones, GSM (Global System for Mobile Communications) phones, and cdmaOne (IS-95A/IS-95B) phones. Modem and cellular data protocol software is provided. Conexants SmartDAA technology (patent pending) eliminates the need for a costly line transformer, relays, and opto isolators typically used in discrete DAA (Data Access Arrangement) implementations. The SmartDAA architecture also simplifies product implementation by eliminating the need for country-specific board configurations enabling worldwide homologation of a single modem board design.
