Broadcom HiGig and HiGig+ protocols use an enhanced XAUI physical layer and tag each packet with a 12-byte HiGig header. HiGig+ extends the XAUI physical layer line rate from 3.125 Gbps up to 3.75 Gbps per lane. The motivation for using the enhanced XAUI physical layer for these protocols is to add switching functionality, such as quality of service (QoS) and link aggregation, that is not available with standard XAUI.
Altera® devices that are compliant with the requirements of HiGig and HiGig+ include:
- Stratix® IV GX FPGAs (up to 32 channels at rates up to 8.5 Gbps, and up to 16 additional channels at rates up to 3.2 Gbps)
- Stratix® IV GT FPGAs (up to 24 channels at rates up to 11.3 Gbps, and up to 24 additional channels at rates up to 6.375 Gbps)
- Arria® II GX FPGAs (up to 16 channels at rates up to 3.75 Gbps)
- HardCopy® IV GX ASICs (up to 24 channels at rates up to 6.5+ Gbps, and up to 12 additional channels at rates up to 3.2 Gbps)
- Stratix II GX FPGAs (up to 20 channels at rates up to 6.375 Gbps)
You can use these devices to implement any interface based on XAUI, HiGig, or HiGig+.
