When the output buffer is set to CMOS mode, these bits determine the output buffer drive
strength. The first number below refers to 3.3 V operation; the second to 1.8 V operation.
These values assume CKOUT+ is tied to CKOUT–.
00: 8mA/2mA
01: 16 mA/4 mA
10: 24 mA/6 mA
11: 32 mA (3.3 V operation)/8 mA (1.8 V operation)

SFOUT2_
REG [2:0]
SFOUT2_REG [2:0].
Controls output signal format and disable for CKOUT2 output buffer. The LVPECL and
CMOS output formats draw more current than either LVDS or CML; however, there are
restrictions in the allowed output format pin settings so that the maximum power dissipa-
tion for the TQFP devices is limited when they are operated at 3.3 V. When there are four
enabled LVPECL or CMOS outputs, the fifth output must be disabled. When there are
five enabled outputs, there can be no more than three outputs that are either LVPECL or
CMOS.
