Quad 2.5GBASE-T Ethernet Networking Controllers RJ45 Front I/O

M.2 NVMe/SATA SSD Mass Storage • USB Front I/O

The SCJ-VEENA is a mezzanine side card for EKF CPU boards, provided with a socket for a PCI Express® based M.2 mass storage module, and four independent 2.5Gbps NBASE-T Ethernet controllers for universal networking.

The SCJ-VEENA is suitable for EKF CPU cards such as the SC5- and PC7-FESTIVAL or SC9-TOCCATA, which are equipped with two HSE (high speed expansion) mezzanine connectors, for eight PCIe® Gen3 or Gen4 lanes.

The M.2 socket can accommodate an NVMe type SSD module up to the 2280 form factor, with a PCIe® x4 Gen3 or Gen4 interface for superior data transfer rates.

Four Intel® I226-IT networking controllers supporting Time Sensitive Networking are wired to RJ45 front panel connectors, and can be operated individually at 10BASE-T, 100BASE-TX, 1000BASE-T and 2.5GBASE-T speed.
