(Hex) Bits Name Description
0x141 0 OUT7 power-down Power-down output (LVDS/CMOS).
0: power on.
1: power off (default).
0x142
[7:5]
OUT8 output polarity
In CMOS mode, Bits[7:5] select the output polarity of each CMOS output.
In LVDS mode, only Bit 5 determines LVDS polarity.

4 OUT8 CMOS B In CMOS mode, turns on/off the CMOS B output. There is no effect in LVDS mode.
0: turn off the CMOS B output (default).
1: turn on the CMOS B output.
3 OUT8 select LVDS/CMOS Selects LVDS or CMOS logic levels.
0: LVDS (default).
1: CMOS.
[2:1] OUT8 LVDS output current Sets output current level in LVDS mode. This has no effect in CMOS mode.
