2. GENERAL DESCRIPTIONS
The MX98715 controller is an IEEE802.3u compliant
single chip 32-bit full duplex, 10/100Mbps highly inte-
grated Fast Ether net combo solution, designed to ad-
dress high performance local area networking (LAN)
system application requirements.
MX98715's PCI bus master architecture delivers the
utilimized perfor mance for future high speed and pow-
erful processor technologies. In other words, the
MX98715 not only keeps CPU utilization low while maxi-
mizing data throughput, but it also optimizes the PCI
bandwidth providing the highest PCI bandwidth utiliza-
tion. To further reduce maintenance costs the MX98715
uses drivers that are backward compatible with the origi-
nal MXIC MX98713 series controllers.
The MX98715 contains a PCI local bus glueless inter-
face, a Direct Memory Access (DMA) buffer manage-
ment unit, an IEEE802.3u-compliant Media Access Con-
troller (MAC), large Transmit and Receive FIFOs, and
an on-chip 10 Base-T and 100 Base-TX transceiver sim-
plifying 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-ne-
gotiation, the MX98715-based adapter allows a single
RJ-45 connector to link with the other IEEE802.3u-com-
pliant device without re-configur ation.
In MX98715, an innovative and proprietary design "Adap-
tive Network Throughput Control" (ANTC) is built-in to
configure itself automatically by MXIC's driver based on
the PCI burst throughput of diff erent PCs. With this pro-
prietary design, MX98715 can always optimize its oper-
ating bandwidth, network data integrity and throughput
f or diff erent PCs.
MXIC MX98715 features Remote-Wake-Up capability
that enables a wide range of wake-up capabilities, in-
cluding the ability to customize the content of specified
packet which PC should to respend to, even when it is in
a low-power state. PCs and workstations could take
advantage of these capabilities of being waked up and
serviced simultaneiously over the network by remote
server or workstation. It helps organizations reduce their
maintenance cost of high-perfor mance business PCs.
With its on-chip support for both little and big endian
byte alignment, MX98715 can also address non-PC
applications.
