描述 Description

Microchip's LAN9730 was specifically designed to provide a high-performance, low-cost USB to 10/100 Ethernet connectivity solution with a Hi-Speed Inter-Chip (HSIC) interface. Taking advantage of the broad availability of existing USB drivers and software, Microchip's proprietary HSIC technology incorporates a 2-pin digital bus that enables the use of USB as a low-power, chip-to-chip interconnect at speeds up to 480 Mbps. The internal device controller is USB 2.0-compliant and the HSIC interface is HSIC USB Electrical Specification Revision 1.0-compliant. The device implements Control, Interrupt and Bulk-in and Bulk-out USB endpoints. Microchip's UniClock? technology simplifies the clocking scheme and reduces system BOM costs by using a single 25MHz crystal for both USB and Ethernet connectivity – without the need for additional components when adding USB hubs.Applications well-suited for the LAN9730 and LAN9730i (industrial temperature range option) include embedded systems, set-top boxes, PVRs as well as USB port replicators and test instrumentation. The LAN9730 also supports auto-negotiation, auto-polarity correction, HP Auto-MDIX? and is compliant with IEEE 802.3 and 802.3u standards. An external MII interface provides support for an external PHY which enables HomePNA? (HPNA) or HomePlug? functionality. Multiple power management features are provided, including various low-power modes, as well as Magic Packet, Wake-on-LAN and Link Status Change wake events. These events can be programmed to initiate a remote USB wakeup. A PCI-like PME wake is also supported when the USB host controller is disabled.?HP Auto-MDIX eliminates the need for special \"crossover\" cables when connecting LAN devices together.Microchip's complimentary and confidential MicroCHECK?design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design.?MicroCHECK?design review service is subject to?Microchip's?Program Terms and Conditions?and requires a myMicrochip?account.
