Interlaken is a scalable protocol that enables chip-to-chip packet transfers at rates from 10 Gbps to 100 Gbps and beyond. Altera’s Interlaken intellectual property (IP) core continues to scale with today’s demand for more bandwidth and higher performance needs. Altera has been a part of the Interlaken Alliance since its inception in 2007 and continues to innovate new protocol features to provide customers with robust and easy-to-implement Interlaken IP solutions. Altera entered the market with 25G Interlaken IP cores and now offers 200G+ Interlaken IP cores.

Accelerating Time to Market with Proven Altera and Cavium
Altera's Interlaken IP core is ideal for multi-terabit routers and switches for access, carrier Ethernet, and data center applications that demand high IP configurability to optimize for system performance and interoperability. The Interlaken IP core also provides the necessary scalability for next-generation platforms. The combination of Altera’s Interlaken IP core in the Stratix® V FPGA with Cavium’s Octeon processors provides high throughput and bandwidth when workloads are at their peak.
To help simplify your design decision process and accelerate your time to market, Altera’s Interlaken IP core on the Stratix V FPGA has been validated with Cavium's Octeon multicore processors. This interoperability assures solution connectivity upfront when you develop with Altera and Cavium.

Altera's Interlaken IP Solution
The Interlaken IP core includes Altera’s technology-leading transceivers (PMA), physical coding sublayer (PCS), and MAC layers. The PCS and PMA layers are hardened within the Stratix V and Arria® V FPGAs, thereby saving customers 30 percent to 50 percent of FPGA logic resources. In addition to resource savings, the Interlaken IP has been through extensive simulation verification and has been proven to work on multiple internal and customer platforms. Altera's Interlaken IP solution has passed the Interlaken Alliance's device interoperability tests. Altera continues to set up interoperability activities with leading ASSP vendors for next-generation platforms.
Altera offers the MegaCore® function-based and customized Interlaken IP solutions. For more information, please contact your local Altera sales representative or email email@example.com.
