2. GENERAL DESCRIPTIONS
The MX98715A controller is an IEEE802.3u compliant
single chip 32-bit full duplex, 10/100Mbps highly inte-
grated Fast Ethernet combo solution, designed to ad-
dress high performance local area networking (LAN)
system application requirements.
MX98715A's PCI bus master architecture delivers the
optimized performance for future high speed and pow-
erful processor technologies. In other words, the
MX98715A not only keeps CPU utilization low while
maximizing data throughput, but it also optimizes the
PCI bandwidth providing the highest PCI bandwidth uti-
lization. To further reduce maintenance costs the
MX98715A uses drivers that are backward compatible
with the original MXIC MX98713 series controllers.
The MX98715A 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-
negotiation, the MX98715A-based adapter allows a
single RJ-45 connector to link with the other IEEE802.3u-
compliant device without re-configuration.
In MX98715A, 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, MX98715A can always optimize its
operating bandwidth, network data integrity and through-
put for different PCs.
The MX98715A features Remote-Power-On and Re-
mote-Wake-Up capability and is compliant with the Ad-
vanced Configuration and Power Interface version 1.0
(ACPI). This support enables a wide range of wake-up
capabilities, including the ability to customize the con-
tent of specified packet which PC should be responded
to, even when it is in a low-power state. PCs and work-
stations could take advantage of these capabilities of
being waked up and served simultaneously over the net-
work by remote server or workstation. It helps organi-
zations reduce their maintenance cost of PC network.
The 32-bit multiplexed bus interface unit of MX98715A
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, MX98715A can also address non-PC appli-
cations.
