GENERAL DESCRIPTION
The Supereal SR9900 10/100M Ethernet controller combines an IEEE 802.3u compliant Media Access Controller (MAC), USB bus controller, and embedded memory. A linear regulator (LDO) is incorporated for reduced BOM cost. With state-of-the-art DSP technology and mixed-mode signal technology, Functions such as Crossover Detection and AutoCorrection, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capabilities. Advanced Configuration Power management Interface (ACPI)—power management for modern operating systems that are capable of Operating System-directed Power Management (OSPM)—is supported to achieve the most efficient power management possible. In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-Up Frame) is supported in both ACPI and APM (Advanced Power Management) environments. WPD helps prevent unwanted/ unauthorized wake-up of a sleeping computer.
