Mode
Normal operation.
Partial power-down, reference on; use only if there are no external load resistors.
Partial power-down, reference on, safe LVPECL power-down.
Total power-down, reference off; use only if there are no external load resistors.

Normal operation.
Partial power-down, reference on; use only if there are no external load resistors.
Partial power-down, reference on, safe LVPECL power-down.
Total power-down, reference off; use only if there are no external load resistors.

Description
In CMOS mode, <7:5> select the output polarity of each CMOS output.
In LVDS mode, only <5> determines LVDS polarity.

In CMOS mode, turn on/off the CMOS B output. There is no effect in LVDS mode.
<4> = 0; turn off the CMOS B output.
<4> = 1; turn on the CMOS B output.
Select LVDS or CMOS logic levels.
<3> = 0; LVDS.
<3> = 1; CMOS.
Set output current level in LVDS mode. This has no effect in CMOS mode.
