Socket 754 Design and Qualification Requirements
Table 3. Summary of Required Measurements for the Socket 754 (Continued)
Measured
Quantity
Propagation delay
skew among
single ended
signals.
Definition
Specified
Value(s)
Ten ps max plus
3 ps max
measurement
error.
Measurement
Applicable
Standard
Use EIA-364-103
standard or provided
in Section 7.4.1.1,
Test Procedure, on
page 34.
Deviation in the
propagation delay
skew of a single
ended signal
through different
mated (single) pins
in the socket.
Time delay of single
ended signal between
the top pads of the
interposer and the pads
on the bottom side
fixture.
The ground return for
the specified signal pin
pattern of single ended
signals is to be located
as specified.
See Figure 6 on page
29 for specified signal
pin patterns, which
also include the
location of the current
return pin.
Propagation delay
skew among
differential signal
pairs.
Deviation in the
propagation delay
skew of differential
signals through
mated pin pairs in
the socket.
Ten ps max plus
3 ps max
measurement
error.
Time delay of a
differential signal
between the top pads of
the interposer and the
pads on the bottom side
of the fixture. The
specified three-pin (S1,
S2, G) arrangement
should be used.
Use EIA-364-103
standard or provided
in Section 7.4.1.1,
Test Procedure, on
page 34. See Figure 6
on page 29 for
specified differential
pin-pair patterns,
which also include the
location of the current
return pin
Frequencies for
the inductance
measurements.
The frequencies at
which inductance is
to be measured.
500 MHz and 2
GHz
Any frequency domain
test equipment
recommended in EIA
standards may be used
to perform the
measurements. If time
domain equipment is
used, it should have
sufficient sampling
rates to resolve the
specified frequencies.
Frequencies for
the capacitance
measurements.
The frequencies at
which capacitance
is to be measured.
500 MHz and 2
GHz
Any frequency domain
test equipment
recommended in EIA
standards may be used
to perform the
measurements. If time
domain equipment is
used, it should have
sufficient sampling
rates to resolve the
specified frequencies.
