characteristics of SFI-4 at the framer. Stratix and Stratix GX devices
support all the timing requirements needed to support transmitter and
receiver functions of a SFI-4 framer; only framer-related timing
specifications are applicable.
For details on the timing specifications of LVDS I/O standards in Stratix
and Stratix GX devices, see the Stratix Device Family Data Sheet section of
the Stratix Device Handbook, Volume 1 and the High-Speed Differential I/O
Interfaces in Stratix Devices chapter or the Stratix GX Device Family Data
