Device Overview
The 89HT0808P Retimer Evaluation Board is designed to enable quick in-system testing of IDT’s 4-lane,
8.0Gbps, PCIe 3.0 Retimer IC product.
The Board features a 4-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 and will train to 4-lanes as active. This Evaluation Board includes a USB
to I
2
C bridge circuit which allows convenient connection to a PC for accessing the Retimer via IDT’s Retimer
Configuration Utility (GUI). An I
2
C connection is also provided for the same control capability, but uses an
external USB to I
2
C adapter 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.
