July 2005 Stratix Device Handbook, Volume 2
Implementing SFI-4 in Stratix & Stratix GX Devices
Tables 9–2 and 9–3 list the number of SFI-4 cores that can be implemented
in Stratix and Stratix GX devices. See the High-Speed Differential I/O
Interfaces in Stratix Devices chapter in the Stratix Device Handbook or the
Stratix GX Device Handbook for the package type and the maximum
number of channels supported by each package.

Note to Ta b le 9 – 2 :
(1) The LVDS channels can go up to 840 Mbps (or 1 Gbps using DPA in Stratix GX
devices). This number includes both high speed and low speed channels. The
high speed LVDS channels can go up to 840 Mbps. The low speed LVDS channels
can go up to 462 Mbps. The High-Speed Differential I/O Support chapters in the
Stratix Device Handbook, Volume 1 and the Stratix GX Device Handbook, Volume 1
and the device pin-outs on the web (www.altera.com) specify which channels are
high and low speed.
