Evaluation Board for 89HT0816P Retimer, 8-lane, 8Gbps, PCIe3

The 89HT0816P Retimer Evaluation Board is designed to enable quick in-system testing of IDT’s 8-lane, 8Gbps, PCIe 3.0 Retimer IC product.

This board features an 8-lane PCIe connection from host through the Retimer to an end-point device installed in the 16-lane PCIe slot. The Evaluation Board is used by inserting it into a desktop PC or server, and then plugging an end point adapter card (SAS, Ethernet, graphics, etc.) into the 16-lane slot on top. Passive trace cards can be used to extend the data signal to emulate a planned system design. Note that the resulting card stack will require an open chassis test environment.

The board provides a USB-to-I2C bridge circuit which allows convenient connection to a PC for accessing the Retimers control and status registers via IDT’s Configuration Utility GUI for Windows. Software tools for signal eye capture are available. Direct I2C and JTAG interfaces are also provided to access all receiver, transmitter, and other device registers.
