The OIF has defined the electrical interface (SFI) between the
SONET/SDH framer and high-speed SERDES devices. To keep up with
evolving transmission speeds and technology enhancements, different
versions of electrical interfaces are defined. SFI-4 is the version of SFI that
acts as an interface between an OC-192 SERDES and SONET framer, as
shown in
direction. With their differential I/O capabilities, Stratix and Stratix GX
devices are ideally suited to support the framer side of the SFI-4 interface.
Support for SFI-4 extends the reach of high-density programmable logic
from the backplane to the PHY devices.
System Topology
The SFI-4 interface uses 16 channels of source-synchronous LVDS to
interface between a SONET framer and an OC-192 SERDES.
