Low Level
Contact
Resistance
(LLCR)
EIA 364-23
The low level contact resistance (LLCR)
measurement is made across the plug and
receptacle mated contacts and does not
include any internal paddle cards or
substrates of the plug or receptacle. The test
boards shall be provided with the connectors
to be tested.
Measure at 20 mV (max) open circuit at 100
mA.
The following requirements apply to the power and
signal contacts:
30mΩ(max) initial
10 mΩ maximum change for post test LLCR
Mate/Un-mate connector, apply 300(Type A)
VDC adjacent terminals or ground.
(EIA-364-21)

Voltage
Drop
The maximum rated VBUS current of the
cable assembly shall be used.
The measurement includes representative
receptacles at both ends of the cable
assembly, mounted on test fixtures.
125mV max drop across power pair from pin to pin.
Connect the cable to test fixture, measure by
TDR.
Measurement configuration is on next page.
Calculates by cable impedance=(2n rate +5n
rate)/2
1.Differential impedance (rt=200ps 10~90%)
76.5 Ohm to 103.5 Ohm
2.Com. Impedance(rt=200ps 10~90%))
21 Ohm to 39 Ohm
Connect connector to attenuation test fixture,
measure by network Analyzer. Measurement
