Teridian announces general sample availability of 78Q8430 10/100 Fast Ethernet Multi-Media Offload Controller for embedded applications
(Technology News, 11 Apr 2008 )
Teridian Semiconductor has announced general sampling of its 78Q8430 10/100 Fast Ethernet Multi-Media Offload Controller for video streaming and mixed media (data, voice and vide over IP) applications. The 78Q8430 targets Ethernet applications requiring reliable connectivity and quality of service levels such as industrial networking, set top box, digital television, and other consumer broadband or audio/video equipment.
The Teridian 78Q8430 is a 10/100BASE-TX controller that seamlessly interfaces to non-PCI processors through a simplified pseudo SRAM-like Host Bus Interface supporting 32/16/8 bit data bus widths. It provides support for IEEE802.3x flow control and compliance with IEEE802.3 and 802.3u standards and employs a unique management scheme for the integrated 32kB SRAM FIFO memory to adaptively allocate memory depending on the data stream load and direction all without host or software driver intervention for reduced host MIPS requirements and lower packet latency.
In addition, the flexible packet classification engine supports up to 128 user configurable rules and by default comes configured with 8 unicast (or perfect) IP address filtering ability, and can be configured for wildcard address filtering, positive/negative filtering, promiscuous mode operation, as well as multicast and broadcast mode operation. Other offload functionality includes 64kB JUMBO packet support, IP Checksum calculation, check/generate/strip/append CRC’s, four levels of transmit priority queuing, and the ability to drop frames based on source IP address.
The 78Q8430 10/100 Fast Ethernet Multi-Media Offload Controller complements Teridian’s consumer electronics offering which include world’s smallest Ethernet phy devices, world’s broadest offering of smart card interfaces and controllers, and the world’s first single package Si DAA modems and voice over IP FXO’s. Teridian Semiconductor recently announced it has supplied ICs in over 100 million set top boxes.
