Socket 754 Design and Qualification Requirements
24850 Rev. 3.07 August 2003
The Equation (2) definition of the differential impedance assumes that the driven (or signal)
conductors have the same geometrical shape
Note
: Equation (2) is only valid for non-symmetric differential lines in homogenous media.
The differential impedance should be measured for all combinations of the three-pin arrangements as
shown in Figure 6 on page 29. The pins are intentionally numbered in a specific manner as to yield
identical

arrangement in Figure 6e on page 29.

7.2.1
Differential Impedance
The following procedures are required to properly test for differential impedance.
7.2.1.1
Test Procedure
Use the procedures shown in EIA-364-108 or see the equations in terms of partial loop
inductance and Maxwell capacitance matrices. If the time domain method is used in
measurement, then the signal should have rise time of 35 to 150 ps for signal amplitude to go
from 10 – 90%.
The differential transmission line impedance for three mated pins, using one pin as the
voltage/current reference.
Any frequency domain test equipment recommended in EIA-364-108 may be used to perform the
measurements.
If time domain equipment is used, it should have sufficient sampling rates to resolve the specified
frequencies.
7.2.1.2
Test Condition
Frequency or Time Domain Method
Time Domain method uses a Rise Time: 35 to 150 ps, 10 to 90%
Frequency Domain method use 500MHz and 2 GHz
The differential impedance measured for a three-pin configuration (S1, S2, G).
7.2.1.3
Requirements
The acceptable range for differential impedance is 100 ± 10%
with an additional ± 2-
measurement error.
