Virtex-6 - GTH - RX Input Sensitivity Measurement Methodology

Description

Under what circumstances was the RX sensitivity (DVPPIN) characterization done?

Solution

As this spec in the data sheet is an absolute minimum, the RX termination will not affect this. 

However, the characterization was measured with all settings and the characterization report published on the external web used an EQ of 4 or 6. 

Also, as there is not significant loss in the test fixture, the RX input sensitivity is very similar for all even settings. 

The DFE for this characterization was turned off.
