1.

Parameter value at 1/4 QPI Refclk

2.

Parameter value at full QPI Refclk

3.

The termination small signal resistance; tolerance over the entire signalling voltage range shall not exceed +/-5 ohms with 

regard to the average of the values measured in the high output voltage state and the low output voltage state for that pin.

4.

HVM guaranteed error free value for stressed PRBS signaling across PVT. LInk BER is the dominant spec of which eye 

dimensions are only one factor, and improving another factor could compensate for eye height or width.

5.

HVM guaranteed error free value for stressed ‘1010 signaling across PVT. Link BER is the dominant spec of which eye 

dimensions are only one factor, and improving another factor could compensate for eye height or width.
