89HT0832P Retimer Evaluation Board 89KTT0832P Kit for 8.0 Gbps, 16-lane PCIe 3.0 Applications

2022-05-27

●Device Overview
■The 89HT0832P Retimer Evaluation Board is designed to enable quick in-system testing of IDT's 16-lane, 8.0 Gbps, PCIe 3.0 Retimer IC product.
■The Board features a 16-lane connection from host through the retimer to an end-point device installed in the upper PCIe slot. Any width adapter card, from a 1-lane SATA card to a 16-lane graphics accelerator, can be plugged into the top-edge PCIe slot. This Evaluation Board includes a USB to I²C bridge circuit which allows convenient connectors to a PC for accessing the Retimer via IDT's Retimer Configuration Utility (GUI). I²C and JTAG connections are also provided giving equivalent control capability, but using an external USB to I²C/ JTAG adapter together with IDT's Retimer GUI. Via the GUI, the device receiver, transmitter and many other configuration parameters can be adjusted to provide optimum operating performance.
■The Evaluation Board is used by inserting it into a desktop PC or server and then plugging an end point card (SATA, Ethernet, USB3, etc.) into the 16-lane slot on top, as shown in the example diagram and photo on the following page. 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. IDT's Technical Applications information can provide configuration for different channel lengths and system architectures.
