DS160PT801X16EVM Riser Card Evaluation Module
The DS160PT801X16EVM is a 16-lane PCIe riser card board intended to be used for evaluation of the
Texas Instruments DS160PT801 PCIe Gen4 retimer. The EVM uses the 1x16 Card Electromechanical (CEM)
connector to enable quick system testing in a standard x16 socket and a standard PCIe endpoint. The evaluation
board may be used with the SigCon Architect software program to provide register control and status information
from the DS160PT801 devices. Contact a local Texas Instruments representative to obtain the SigCon Architect.
