Tabula's I-100 device provides a bridge between 100Gbps Ethernet and Interlaken, the ascending
interconnect standard for communications. Interlaken provides a low pin-count interface for packet and
cell transfer between devices or between devices and a module, for aggregate bandwidths exceeding
160Gbps. 100 Gigabit Attachment Unit Interface (CAUI) provides a low pin-count board-level interface to
connect a 100 Gigabit device to a module.
The I-100, when combined with three quad PHYs, provides a flexible and cost effective bridge from a 20-lane Interlaken interface to a CAUI interface. This provides a generic solution to meet multiple design requirements including device bridging such as NPU to Ethernet switch, and serial backplane applications. The I-100 device's Interlaken interface is compliant with the Interlaken Protocol Definition Revision 1.1 and the Interlaken Interoperability Recommendation Revision 1.2. The interface implements 20 6.25Gbps transmit receive SerDes channels and a low-speed transmit receive out-of-band status interface. The I-100 implements a 2.5MByte FIFO on the MAC receive path (CAUI to Interlaken). This high level of memory integration provides buffering for over 250 Jumbo Ethernet frames (9KByte frame) resulting in loss-less flow control across the CAUI interface with per-class flow control without any external DRAM. The complete solution was developed in partnership with NetLogic Systems to deliver a solution that is both cost effective and meets the highest signal-integrity standards. I-100 Bridge Brochure >
