78Q8430 10/100 Ethernet  
MAC and PHY  
Simplifying System Integration TM  
DATA SHEET  
March 2009  
DESCRIPTION  
FEATURES  
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.  
Single chip 10Base-T/100Base-TX  
IEEE-802.3 compliant MAC and PHY  
.
.
.
Adaptive 32 kB SRAM FIFO memory  
allocation between Tx and Rx paths  
Queue independent user settable water  
marks  
Per queue status indication  
Address Resolution Controller (ARC)  
.
Multiple perfect address filtering: 8 default  
(max 12)  
.
Wildcard address filtering, individual,  
multicast and broadcast address  
recognition and filtering  
.
Positive/negative filtering and promiscuous  
mode  
Supporting 10Base-T and 100Base-TX, the  
transceiver provides Auto MDI-X cable  
64 kB JUMBO packet support  
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.  
QoS: 4 Transmit priority levels  
Non-PCI pseudo-SRAM Host Bus Interface  
.
.
8-bit, 16-bit and 32-bit bus width  
Big/little endian support for 16-bit/32-bit bus  
widths  
Asynchronous (100 MHz) and synchronous  
(50 MHz) bus clock support  
.
Low power and flexible power supply  
management  
.
.
Power down/save  
Wake on LAN (Magic Packet™, OnNow  
packet)  
BENEFITS  
.
Link status change  
Support for IEEE-802.3, IEEE-802.3u and  
IEEE-802.3-2000 Annex 31.B  
Traffic Offload Engine Functionality  
.
.
Transfer frame: APF & ICMP Echo  
IP Firewall configuration: drop frames on  
source IP address  
Low host CPU utilization/overhead with  
minimal software driver overhead and small  
driver memory space requirements  
.
IP Checksum  
Improved packet processing, low latency and  
low host CPU utilization  
Available in an industrial temperature range  
(-40 °C to +85 °C)  
RoHS compliant (6/6) lead-free package  
Highest performance streaming Video over IP  
Optimized performance in mixed media  
application such as video, data and voice  
APPLICATIONS
