011 = Not Used
100 = 3.0mA LVDS Output Driver Current
101 = 2.5mA LVDS Output Driver Current
110 = 2.1mA LVDS Output Driver Current
111 = 1.75mA LVDS Output Driver Current
TERMON
0 = Internal Termination Off
1 = Internal Termination On. LVDS Output Driver Current is 2x the Current Set by ILVDS2:ILVDS0. Internal termination should only be
used with 1.75mA, 2.1mA or 2.5mA LVDS output current modes.
OUTOFF
0 = Digital Outputs are enabled.
1 = Digital Outputs are disabled.
