Evaluation Board SDK for the 89H48T12G2

The 89EBPES48H12G2 Evaluation Board provides an evaluation platform for the PES48H12G2 and the PES48T12G2 switch. It is also a cost effective way to add PCIe ports (slots) to an existing system with limited number of PCIe ports/slots. The EB48H12G2 board is designed to function as an add-on card to be plugged into a x8 PCIe slot available on a motherboard hosting an appropriate root complex and microprocessor(s). The EB48H12G2 is a vehicle to test and evaluate the functionality of the PES48H12G2 switch. It is also designed to work with the PES48H12 (Gen 1) switch. Refer to application note AN-550 for detail information on Designing Gen2-Ready boards for IDT’s 4+E298-lane, 12-port PCIe Switches. Customers can use this board to get a headstart on software development prior to the arrival of their own hardware. The EB48H12G2 is also used by IDT to reproduce system-level hardware or software issues reported by customers.
