Universal Flite Optimizer Universal Full-Rate ADSL System Chipsets for CPE Features Overview n Compliant with -- -- -- -- The Universal Flite OptimizerTM is a chipset for a full-rate ADSL modem, consisting of only two chips, a DSP chip and an analog front end. ITU G.992.1 (G.dmt) ITU G.992.2 (G.lite) ITU G.994.1 (G.hs) ANSI T1.413 Issue 2 n Supports Annex A and Annex C1 n Supports all framing modes per G.992.1 n Supports G.dmt, G.lite and T1.413 i2 through auto-detect feature n Annex A operation -- -- Up to 8 Mbps downstream, 1 Mbps upstream for G.dmt mode Up to 1.5 Mbps downstream, 512 kbps upstream for G.lite mode n Annex C operation -- Excellent performance for FBM (FEXT bitmap) and DBM (dual bitmap) modes n Support for dual latency for G.dmt mode n Host-based Soft SAR consumes minimum CPU time n PCM interface for STM and voice applications Benefits n Small form factor reduces PC board space requirements n Lowest power dissipation n Software upgradeable, eliminates costly hardware upgrades n Lowest BOM, requires only two additional active components n Reference designs available, with software stacks, for fast time to market 1. Flite Optimizer available to support Annex A only markets. The chipset incorporates all silicon functions from the PC interface to the hybrid circuitry for an ITU G.992.1-compliant full-rate ADSL (asymmetric digital subscriber line) modem and provides a costeffective, small-footprint, low-power solution. This solution requires only two additional active components, an EEPROM and a line driver. No external memory, controller, or VCXO are required, thus reducing the BOM cost. Through the choice of software drivers and few passive components, the chipset can be configured for either Annex A or Annex C operation. The chipset integrates an efficient power management scheme, which guarantees lowest power consumption. The operating efficiency and programmability of the chipset ensure long product lifetime and avoid the need for costly hardware upgrades. Software stacks are provided to support PPP-overATM, PPP-over-Ethernet, RFC 1483, and IP-overATM network protocols. The Universal Flite Optimizer software drivers support Microsoft Windows 95, Windows 98, Windows 98 Second Edition, Windows 2000, and Windows Millennium (once available) Operating Systems. The ATM SAR function is supported via host processing with minimum impact on the host CPU. Since the modem function is independent of the host CPU, there is no deterioration in PC performance.
