2. GENERAL DESCRIPTIONS
The MX98715AEC-E controller is an IEEE802.3u compliant single chip 32-bit full duplex, 10/100Mbps highly integrated Fast Ethernet combo solution, designed to address high performance local area networking (LAN) system application requirements. MX98715AEC-E's PCI bus master architecture delivers the optimized performance for future high speed and powerful processor technologies. In other words, the MX98715AEC-E not only keeps CPU utilization low while maximizing data throughput, but it also optimizes the PCI bandwidth providing the highest PCI bandwidth utilization. To further reduce maintenance costs the MX98715AEC-E uses drivers that are backward compatible with the original MXIC MX98713 series controllers. The MX98715AEC-E contains a PCI local bus glueless interface, a Direct Memory Access (DMA) buffer management unit, an IEEE802.3u-compliant Media Access Controller (MAC), large Transmit and Receive FIFOs,
and an on-chip 10 Base-T and 100 Base-TX transceiver simplifying system design and improving high speed signal quality. Full-duplex operation are supported in both 10 Base-T and 100 Base-TX modes that increases the controller's operating bandwidth up to 200Mbps. Equipped with intelligent IEEE802.3u-compliant auto-negotiation, the MX98715AEC-E-based adapter allows a single RJ-45 connector to link with the other IEEE802.3ucompliant device without re-configuration. In MX98715AEC-E, an innovative and proprietary design "Adaptive Network Throughput Control" (ANTC) is built-in to configure itself automatically by MXIC's driver based on the PCI burst throughput of different PCs. With this proprietary design, MX98715AEC-E can always optimize its operating bandwidth, network data integrity and throughput for different PCs. The MX98715AEC-E features Remote-Power-On and Remote-Wake-Up capability and is compliant with the Advanced Configuration and Power Interface version 1.0

MX98715AEC-E
(ACPI). This support enables a wide range of wake-up capabilities, including the ability to customize the content of specified packet which PC should be responded to, even when it is in a low-power state. PCs and workstations could take advantage of these capabilities of being waked up and served simultaneously over the network by remote server or workstation. It helps organizations reduce their maintenance cost of PC network. The 32-bit multiplexed bus interface unit of MX98715AEC-E provides a direct interface to a PCI local bus, simplifing the design of an Ethernet adapter in a PC system. With its on-chip support for both little and big endian byte alignment, MX98715AEC-E can also address non-PC applications.
