DS25CP102EVK User Manual 

  

This section provides recommended test setup procedure for the device evaluation. Figure 3 
depicts a typical setup and instrumentation you may use for the device evaluation. 

  
1.  Configure the test setup as shown in Figure 3. 

 

2.  Set and enable the desired INn to OUTn drivers by selecting SEL0, SEL1, EN0 and EN1 

according to Tables 1 – 2.  

 

3.  Apply + supply (3.3V typical) to the VDD and – supply (ground) to the VSS connectors.  

 

4.  Set desired pre-emphasis and/or equalization levels according to Tables 3 – 4. 

 

5.  Connect a signal source (signal generator, data source, or an LVDS driver) to the desired 

INn inputs on the board and adjust the signal parameters (VOH, VOL, VCM) so that they 
comply with the device input recommendations. 

 

6.  Connect an oscilloscope to the selected OUTn outputs and view the output signals with 

an oscilloscope with the analog bandwidth of at least 5 GHz.
