Overview

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.

What is interlaken?

Morten Kofoed Esbjørn Oct 31 2022, Interlaken provides a standardized serial interface that is agnostic of underlying SerDes implementations. It ensures reliable transfer of data over a configurable number of physical connections and can be configured to support multiple lane configurations. The Interlaken protocol provides mechanisms to ensure the integrity of data transfer as well as manage data flows to ensure that the chip is not overloaded. These mechanisms effectively increase the...

Unlock your chips full data throughput potential with Interlaken

Piotr Koziuk Sep 12 2022, Way back in the early 2000's when XAUI was falling short on link flexibility a search for an alternative chip-to-chip data transfer interface with SPI like features, lead Cisco Systems and Cortina System to put forward the proposal for the Interlaken standard. The new standard married the best of XAUI’s serialized data and SPI’s flow control capabilities. To this day the continuous growth in data consumption is driving demand for higher speeds, but also lower...
