Hardware Description and Setup
The general procedure for setting up and testing with the DS250DF810 Evaluation Module
(DS250DF810EVM) hardware is as follows:
1. Check the EVM jumper settings to ensure they match
below.
2. Connect the EVM to a PC using the provided USB cable.
3. Connect 3.3V power (2A max) as shown below. The EVM has an on-board 3.3V-to-2.5V regulator to
supply the Retimer with the required 2.5V.

Communications
4. Connect the EVM to the system under test.
The default EVM configuration has four differential RX inputs and four differential TX outputs accessible to
the user. Connect the RX and TX signals to the test channel using Huber+Suhner 1x8 MXP cable
assemblies (See
for ordering information).
NOTE:
All TX and RX channels are AC coupled with physical 220 nF capacitors on the package of
the device, so external AC coupling capacitors are not needed when using this EVM.
