Software Implementation
The SFI-4 interface uses a 16-bit LVDS I/O interface. The Altera
Quartus
allowing you to implement LVDS I/O buffers through the Quartus II
Assignment Organizer.
For information on the Quartus II Assignment Organizer, see the
Quartus II Software Help.
Conclusion
SFI-4 is the standard interface between SONET framers and optical
SERDES for OC-192 interfaces. With embedded SERDES and fast PLLs,
Stratix and Stratix GX devices can easily support the SFI-4 framer
interface, enabling
10-Gbps (OC-192) data transfer rates. Stratix and Stratix GX I/O supports
the required data rates of up to 622.08 Mbps. Stratix and Stratix GX fast
PLLs are designed to support the high clock frequencies and one-to-one
relationship needed for interfaces such as XSBI and SFI-4. Stratix and
Stratix GX devices can support multiple SFI-4 functions on one device.
