Description
When the output mode is CMOS, the bit inverts the relative phase between the two
CMOS output pins. Otherwise, this bit is nonfunctional.
0 (default) = not inverted.
1 = inverted.
Invert the polarity of OUT1.
0 (default) = not inverted.
1 = inverted.
OUT1 output drive capability control.
0 (default) = CMOS: low drive strength; LVDS: 3.5 mA nominal.
1 = CMOS: normal drive strength; LVDS: 7 mA nominal.
OUT1 operating mode select.
000 = CMOS (both pins).
001 = CMOS (positive pin), tristate (negative pin).
010 = tristate (positive pin), CMOS (negative pin).
011 (default) = tristate (both pins).
100 = LVDS.
101 = LVPECL.
110 = reserved.
111 = reserved.
