Interlaken is a high-speed serial communication protocol for chip-to-chip packet transfers. The Altera
®
50G Interlaken MegaCore
®
function implements the Interlaken Protocol Specification, Revision 1.2 . It
supports eight lanes at a lane rate of 6.25 gigabits per second (Gbps), on Stratix
®
V, Arria
®
V GZ, and
Arria 10 devices, providing raw bandwidth of 50 Gbps.
Interlaken provides low I/O count compared to earlier protocols, supporting scalability in both number of
lanes and lane speed. Other key features include flow control, low overhead framing, and extensive
integrity checking. The 50G Interlaken MegaCore function incorporates a physical coding sublayer (PCS),
a physical media attachment (PMA), and a media access control (MAC) block.
