USB 3.0 compatible high speed hub IP core with analog and digital PHY options

January 31, 2012 // By Julien Happich
Evatronix has announced a synthesizable USB high speed hub that supports the high speed mode requirements of the USB 3.0 Hub specification, and features an aggressive power management function provided by Link Power Management (LPM) mode for all supported speed rates. The synthesizable IP offers single or multiple transaction translators and a configurable number of downstream ports (up to 15).

For further customization of the hub, all its descriptors can be configured to the designer’s liking. Thanks to its customizable architecture the hub can be provided in three versions: as a bare version with repeater-enhanced UTMI+ outputs, as a digital PHY enabled IP with pre-configured upstream and downstream UTMI PHY digital logic or as a complete, standalone hub targeted for particular technology together with the Evatronix’ USBHS-PHY.
The Low Power Management (LPM) feature secures the hub's compatibility with the USB 3.0 specification and thus enables designers to include the hub in the USB 3.0 hub IP as a part responsible for High, Full, and Low Speed transfers. For immediate prototyping, a proprietary board can be delivered with test chip PHYs. With its CPU-less architecture, the design is ready for verification and testing in developer’s environment right out of the box.
