High Swing - Alters the repeaters differential output swing to accommodate for PCB /
connector loss. By default, the repeater uses "Normal" swing. "High" swing may be
required when tapping between long backplanes or extended cable distances:
•
Normal Swing: 440 mV min and 660 mV max (peak to peak)
•
High Swing: 800 mV min and 1200 mV max (peak to peak)
OOB Idle Sensitivity - Alters the repeaters OOB detection behavior to accommodate for
marginal OOB signal amplitude in SAS devices under test. The OOB idle sensitivity offers
an adjustable threshold for detecting an inbound OOB sequence. If two PHYs fail to
complete OOB, users may find lowering the OOB idle sensitivity provides a mechanism
for establishing the link even when the OOB signals from the DUT are marginal.

Normal - 100mV to 200mV

Decrease 30mV
• Decrease 60mV
