LAN/Soft V.92 Modem Combo with Integrated Physical Layer Device Set for PCI/Mini PCI CX81210 Network Controller and CX20493 SmartDAAä 3 Line Side Device Overview Features The Conexantä low-cost LAN/Soft V.92 Combo Device set with Conexant’s integrated physical layer technology and third generation SmartDAAä technology (SmartDAA 3) supports 10/100 Ethernet networking and host-processed V.92 analog data modem with V.44 data compression/14.4 kbps fax modem operation. By combining the MAC, PHY and modem system side device into one device, this device set constitutes the most compact, lowest cost Ethernet/soft V.92 chipset in existence. Only two chips are needed to accomplish the level of communication functionality that previously took three or even four devices. This device set is ideal for applications in the notebook, “broadband ready” consumer desktop, and SOHO desktop PC markets requiring a low-cost, flexible LAN/modem communications solution. General Features This device set consists of a CX81210 Network Controller with Integrated Physical Layer device in a 208-ball fine pitch ball grid array (FPBGA) and a CX20493 SmartDAA 3 Line Side Device (LSD) in a 28-pin quad flat no-lead (QFN) package. (Table 1). A simplified device set interface is illustrated in Figure 1. The CX81210 Network Controller contains an integrated PHY device, provides a direct PCI bus connection to the host processor, and connects to the Conexant CX20493 SmartDAA 3 device through the OEM-supplied DIB for connecting to the PSTN/GSTN telephone line in the U.S./Japan/Canada and worldwide. The CX81210 Network Controller integrates internal circuits into a single VLSI (very large scale integration) die. Internal circuits include clock, ARM7 processor, PCI Bus interface logic, control and status registers, ROM, RAM, IEEE 802.3-compliant Media Access Control (MAC), MII, IEEE 802.3-compliant PHY Transceiver, SmartDAA 3 system side device (SSD), general purpose input/output registers, and internal ringwake filter. • Optimized integrated LAN interface/soft V.92 modem for lowcost solution − IEEE 802.3 10BASE-T and 100BASE-TX MAC and PHY − Host-processed (soft) V.92 modem − Concurrent operation of LAN and modem functions − Glueless 32-bit PCI master interface − PXE using BIOS ROM − DMI 2.0 compliant − Integrated power management functions − Modem hardware incorporates Conexant SmartDAA technology and proprietary soft modem buffering − Dual +3.3 V (analog) and 1.8 V (digital power supplies for low power CMOS implementation (Continued on Page 3) Modem data pump and controller functions are processed in a Pentium MMXcompatible PC using host-signal processing modem software (i.e., soft modem). In ITU-T V.92/V.90/K56flex data mode, the modem can receive data at speeds up to 56 kbps from a digitally connected V.92/V.90 or K56flex-compatible central site modem. A V.92/V.90/K56flex modem takes advantage of the PSTN which is primarily digital except for the client modem to central office local loop and are ideal for applications such as remote access to an Internet Service Provider (ISP), on-line service, or corporate site. In this mode, the modem can transmit data at speeds up to 48 kbps in V.92 mode or up to V.34 rates in V.90 mode. (Continued on Page 3) Product Summary Conexant Doc.

Data compression (V.44/V.42 bis/MNP 5) and error correction (V.42/MNP 2-4) modes are supported to maximize data throughput and data transfer integrity. V.44 is a more efficient data compression than V.42 bis that significantly increases downstream throughput thus reducing the download time for the types of files associated with Internet use, such as Web pages and uncompressed data such as in graphics, image, audio, and document files. V.44 data compression can achieve compression rates of more than 25% over V.42bis. Typical compression ratio for V.44 on Web type data is approximately 6-1 resulting in overall effective data throughput rate up to 300 kbps for a 56-kbps connection. Non-error-correcting mode is also supported. Conexant's SmartDAA 3 technology also offers the following advantages over discrete and other silicon DAAs: • • • • • • • Incorporating Conexant’s proprietary DIB design (patent pending) and other innovative DAA features, the SmartDAA 3 architecture simplifies application design, minimizes layout area, and reduces component cost for worldwide support. The SmartDAA 3 architecture eliminates the need for a costly line transformer, relays, and opto-isolators typically used in discrete DAA (Data Access Arrangement) implementations. Product implementation is also simplified by eliminating the need for country-specific board configurations enabling worldwide homologation of a single modem board design. The SmartDAA 3 system-side-powered DAA operates reliably without drawing power from the line and operates on long loops and poor line conditions. The SmartDAA 3 uses a fully differential digital interface which provides robust performance in the presence of common mode noise. Many SmartDAA 3 functions are software configurable providing a flexible solution to often changing worldwide regulations. Enhanced features, such as monitoring of local extension status without going off-hook, are also supported. For over a decade, Conexant has assisted customers with DAA technology and homologation. This expertise and system level approach has been leveraged in this product. 101884B • • Remote audio recording and remote audio playback over the telephone line interface is supported using ALaw, µ-Law, or linear coding at 8000 Hz sample rate to support applications such as digital telephone answering machine (TAM) and voice annotation. Fax Group 3 send and receive rates are supported up to 14.4 kbps with T.30 protocol. V.80 synchronous access mode supports hostcontrolled communication protocols, e. g., H.324 video conferencing. Mini-PCI and PCI reference design kits are available to minimize application design time and costs.
