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.
