Default Notes/
Comments
Antialiasing filter
cutoff (global).
LNA force offset
correction
(local).
LNA and PGA
gain adjustment
(global).
LNA bias current
adjustment
(global).
Configures the
outputs and the
format of the data
(Bits[7:3] and
Bits[1:0] are global;
Bit 2 is local).
Determines LVDS
or other output
properties. Pri-
marily functions to
set the LVDS span
and common-
mode levels in
place of an
external resistor
(Bits[7:1] are global;
Bit 0 is local).
On devices that
utilize global
clock divide,
determines which
phase of the
divider output is
used to supply
the output clock.
Internal latching
is unaffected.
Select internal
reference
(recommended
default) or external
reference (global).
