| LU97--AC-Link Soft Modem Chip Set FEATURES I INTRODUCTION The LU97 chip set is an integrated direct access arrangement (DAA) that provides a programmable line interface to meet international telephone line requirements. The LU97 chip set is available in two 16-pin small outline packages (AC`97 interface on CSP1037 and telephone line interface on CSP1037A/B). The chip set eliminates the need for an AFE, an isolation transformer, relays, opto-isolators, and a 2-wire to 4-wire hybrid. The LU97 chip set dramatically reduces the number of discrete components and cost required to achieve compliance with international regulatory requirements. The CSP1037 complies with AC`97/MC`97 Interface Specification Rev. 2.1. Operating system support: -- Windows1 95, 98, 2000 -- PC `99 compliant -- ACPI compliant High-speed data mode capabilities: -- ITU-T V.90 data rates 28000 bits/s-- 56000 bits/s2 -- Ultrahigh compression throughput due to parallel access directly to the host PC -- ITU-T V.34 extended rates: 33600 bits/s-- 2400 bits/s V.32terbo, V.32bis, and fallbacks -- TIA/EIA 602 standard for AT command set -- V.42 error correction (LAPM and MNP3) -- V.42bis and MNP Class 5 data compression FAX mode capabilities: -- ITU-T V.17, V.29, V.27ter, and V.21 Ch 2 -- TIA/EIA4 578 Class 1 FAX Video-ready modem interface (VRM) V.80 Complete DAA includes the following: -- AC`97/MC`97 2.1 compliant -- International line interface -- Compliant with FCC, CTR21, JATE, and other PTTs -- 3.3 V to 5 V power supply -- 2400 V isolation -- Integrated ring detector -- Integrated analog front end (AFE) -- 2-wire to 4-wire hybrid -- Low-power standby mode -- Low-profile SOIC packages Applications: -- Modem riser cards -- Mobile daughter cards I I I I I 1. 2. 3. 4.

FUNCTIONAL DESCRIPTION The LU97 chip set is an integrated chip set that provides a low-cost, isolated, silicon-based MC`97 compliant interface to the telephone line. The chip set saves cost and board area by eliminating the need for a modem AFE or serial codec. It also eliminates the need for an isolation transformer, relays, opto-isolators, and a 2-wire to 4-wire hybrid. The LU97 chip set complies with AC`97/MC`97 Interface Specification Rev. 2.1. The chip set is fully programmable to meet worldwide telephone line interface requirements, including those described by CTR21, JATE, FCC, and various country-specific PTT specifications. The programmable parameters of the LU97 chip set include ac termination, dc termination, ringer impedance, and ringer threshold. The LU97 chip set has been designed to meet stringent worldwide requirements for out-of-band energy, billing-tone immunity, lightning surges, and safety requirements.
