Mil1394 OHCI Link Layer Controller IP Core

The New Wave DV Mil1394 OHCI Link Layer IP Core provides a complete IP solution for the OHCI layer of the Mil1394 protocol.

The core includes all functionality needed to meet the Mil1394 specification including: Asynchronous Transmit, Isochronous Receive, Start of Frame (STOF) handling, STOF regulated transmit functions, Self ID, and CRC generation/checking.

At the PHY-Link interface, the core is built for connecting to any PHY implementing the defined standard PHY-Link interface. This interface is compatible with the New Wave DV PHY IP core as well as discrete

This core is targeted towards Mil1394 aerospace applications and has been used on a wide range of parts at varying operating rates. The core comes with test-benches and example code, making design integration a straightforward task.

Evaluation versions of the OHCI Link Layer IP Core are available and New Wave DV has a set of standard form factor boards featuring FPGAs, 1394b connectors and transformers, and off-the-shelf reference designs for quick evaluation of the OHCI Link Layer IP Core.
