VOL
The input comparator low voltage level into the pin.
VT/VCOM
The termination voltage when input termination is enabled.
If input termination is disabled, driver is in high impedance.
IOH
The sink current when active load is enabled.
IOL
The source current when active load is enabled.
VCH
The reflection voltage clamp level for high range.
VCL
The reflection voltage clamp level for low range.
Table 6: PE Level Setting
When differential comparator is enabled, odd pins (pins 1, 3, 5, 7, 9 and 11) will be disabled. The
voltage difference between Pin 0 and Pin 1, for example, will be fed to the comparator of Pin 0
only.
Active load termination is a constant current source. If the external output voltage (e.g. from
device-under-test) is more than VT, the pin will sink IOH current, otherwise, the pin will source
IOL current.
