USB 3.0 Hub

特色

• Complies with USB 3.0 standard for Super-Speed (5.0 Gbps), Hi-Speed (480 Mbps), Full-Speed (12Mbps) and Low-Speed (1.5 Mbps).
• Backward compatible with USB2.0 devicesand hubs and the type A connectors.
• Technology and P rocessindependent.
• Data Interface is Dual-simplex, 4-wire differential signaling, separate from USB2.0 signaling with downstream connect / disconnect detection.
• Supports Super speed UTMI transceiver interface with extension to the existing UTMI Interface for USB2.0
• Super-S peed Hub3.0 consists of Hub Forwarder/Repeater and a Hub Controller.
• Separate Header Buffers for each Upstream and Downstream Port’s traffic Forwarding / Repeating.
• Compatible USB transfersupport for Control and Interrupt transfers to USB3.0 Hub using USB3.0 Transaction / Handshake Packets and the Data Packets.
• Super-speed Independent Data Packet Buffering and Concurrent transactionsin both Upstream and Downstream directions
• Bus Transaction protocol is host directed and has asynchronous trafficflow . The packet traffic is explicitly routed.
• Store and Forward morethan one data packets at the same time.
• End-to-End Protocol will retry for recovery.
• Support all standard and Hub specific control transfer requests.
• Super-speed Repeater / Forwarder reclock packets in both the directions.
• Supports suspend and resume signaling and also handle Hub Power Management.
• Utility for wiring of parameterizable downstream Ports, its routing and descriptor generation.
• Fully synthesizable.
