USB 3.0 Hub

Key Features

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.
