EX60T-C71P Datasheet, PDF (9/12 Pages) Hirose Electric – High-Speed Differential Signal Connectors

sTechnical Notes 1
qEye Pattern Waveforms
These eye pattern waveforms are from connectors harnessed with 2 m of twinax cable for high-speed
differential signal applications.
Input Waveform
Output Waveform
qImpedance Characteristics
These differential impedance characteristics have been measured with 45 ps rise time pulses.
The impedance drops slightly in the vicinity of the connector coupling portion.
