Interlaken is a scalable chip-to-chip protocol, which ensures the integrity of reliable data transfer and managing data flows to prevent data overload. The Interlaken IP core is a highly optimized silicon and PHY agnostic implementation of the Interlaken Protocol version 1.2 targeting both ASICs and FPGAs. Our Interlaken controller supports up to 2.6 Tbps high-bandwidth performance and comes with an integrated Media Access layer.

The Interlaken Controller can be widely used in chip-to-chip transfers, it has an extensive feature-set available and allows scalability in number of logic channels (up to 2048), lanes (up to 48) and lane speed (up to 56 Gbps). The IP core is heavily tested in SystemVerilog random regression environment.
