78Q8430 10/100 Ethernet
MAC and PHY
Simplifying System Integration TM
DATA SHEET
DESCRIPTION
The Teridian 78Q8430 is a 10/100 Fast Ethernet
controller supporting multi-media offload. The
device is optimized for host processor offloading
and throughput enhancements for demanding
multi-media applications found in Set Top Box,
IP Video and Broadband Media Appliance
applications. The 78Q8430 seamlessly
interfaces to non-PCI processors through a
simplified pseudo SRAM-like Host Bus Interface
supporting 32/16/8 bit data bus widths.
Supported features include IEEE802.3x flow
control and full IEEE802.3 and 802.3u standards
compliance.
Supporting 10Base-T and 100Base-TX, the
transceiver provides Auto MDI-X cable
cross-over correction, AUTO Negotiation, Link
Configuration and full/half duplex support with
full duplex flow control. The line interface
requires only a dual 1:1 isolation transformer.
Numerous packet processing and IP address
resolution control functions are incorporated,
including an extensive set of Error Monitoring,
Reporting and Troubleshooting features. The
78Q8430 provides optimal 10/100 Ethernet
connectivity in demanding video streaming and
mixed-media applications.
BENEFITS
Support for IEEE-802.3, IEEE-802.3u and
IEEE-802.3-2000 Annex 31.B
Low host CPU utilization/overhead with
minimal software driver overhead and small
driver memory space requirements
Improved packet processing, low latency and
low host CPU utilization
Highest performance streaming Video over IP
Optimized performance in mixed media
application such as video, data and voice
Ease of use, faster development cycles, high
throughput
Optimized power conservation with automatic
turn on when needed
Reduced host CPU utilization and overhead
Improved packet processing
Optimized performance in mixed media
applications
