AsiaInfo launches new dual-port Ethernet control chip
AsiaInfo launches new dual-port Ethernet control chip ASIX Electronics recently announced that it will add two Ethernet control chips for the Embedded Ethernet series of embedded network applications: AX88742 and AX88783, which has built-in dual-port 10 / 100Mbps Ethernet physical layer (PHY), media The access controller (MAC) and network-managed layer 2 switch can be connected to any microcontroller using the third port. AX88742 can be used with a microcontroller with a 32-bit PCI bus, and AX88783 can be used with a microcontroller with a general 8/16 / 32-bit bus. Engineers will provide dual-port Ethernet connectivity for embedded systems, and access remotely located voice, video, and data through the network. AX88783 is a dual-port Ethernet switch, and the third port is a Non-PCI / SRAM-like host interface. AX88742 is also a dual-port Ethernet switch, but the third port is a 32-bit / 33MHz PCI host interface. The built-in Layer 2 switch supports non-blocking wire-speed packet forwarding, and also provides advanced switch specifications, including tag / port-based virtual local area network, spanning tree, service quality priority management, flow control, port security , Port mirroring, IGMP snooping and MIB counters. AsiaInfo's new chips target high-performance embedded system applications, which require dual-port Ethernet to connect to local area networks and wide area networks. In addition, AX88742 / AX88783 supports HP Auto-MDIX, which can connect direct or crossover cables to the device, eliminating the confusion of end users speculation. With the advent of the global broadband generation and the gradual popularization of digital home entertainment applications, consumers' demand for accessing remotely located video, voice, and data via the network has increased. Based on the advantages of ease of use, low price, high frequency bandwidth, high stability, good security, and good compatibility, Ethernet has become a ubiquitous networking method, and gradually surpasses the original SOHO and enterprise network applications, and enters consumer electronics Field, and become the most attractive embedded system networking technology. In addition, Ethernet has further expanded to the factory and meets the needs of industrial applications for networking with high stability and security. AX88742 / AX88783 is suitable for existing and emerging dual-port Ethernet applications, such as VoIP phones / ATA converters, network cameras, next-generation IP set-top boxes / IP TVs, industrial controllers / network sensors, port redundancy / port monitoring, and Single Board Computer (SBC). To help customers design and develop various applications based on these two chips, AsiaInfo provides complete design support services for AX88742 / AX88783, including software and hardware development application files, user manuals, reference circuit diagrams, printed circuit board wiring diagrams and Windows for / Linux / WinCE operating system driver.
Jet pump AC motors are commonly used to power commercial, industrial, centrifugal, and hydraulic pumps. They have shaft slingers and gasketed conduit boxes to help in protecting against moisture and contamination. These motors have enclosures that help protect them from moisture
