Simplifying System Integration

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.
