Determines
LVDS or other
output properties.
Primarily func-
tions to set the
LVDS span and
common-mode
levels in place of
an external
resistor.
On devices that
utilize global
clock divide,
this register
determines
which phase
of the divider
output is used
to supply the
output clock.
Internal latching
is unaffected.
User-defined
pattern, 1 LSB.
User-defined
pattern, 1 MSB.
User-defined

User-defined
pattern, 2 MSB.
Serial stream
control. Default
causes MSB first
and the native
bit stream
(global).
Used to power
down individual
sections of a
converter (local).
