1.4 REGISTER DESCRIPTION
Three write-only registers provide several control and con-
figuration options in the Extended Control Mode. These reg-
isters have no effect when the device is in the Normal
Control Mode. Each register description below also shows
the Power-On Reset (POR) state of each control bit.

DCS:Duty Cycle Stabilizer. When this bit is
set to 1b , a duty cycle stabilzation circuit is
applied to the clock input. When this bit is set
to 0b the stabilzation circuit is disabled.
POR State: 1b
DCP: DDR Clock Phase. This bit only has an
effect in the DDR mode. When this bit is set
to 0b, the DCLK edges are time-aligned with
the data bus edges ("0 Phase"). When this
bit is set to a 1b, the DCLK edges are placed
in the middle of the data bit-cells ("90
Phase").
POR State: 0b
nDE: DDR Enable. When this bit is set to 0b,
data bus clocking follows the DDR (Double
Data Rate) mode whereby a data word is
output with each rising and falling edge of
DCLK. When this bit is set to a 1b, data bus
clocking follows the SDR (single data rate)
mode whereby each data word is output with
either the rising or falling edge of DCLK , as
determined by the OutEdge bit.
POR State: 0b
Bit 11
Bit 10
Bit 9
OV: Output Voltage. This bit determines the
LVDS outputs’ voltage amplitude and has the
same function as the OutV pin that is used in
the normal control mode. When this bit is set
to 1b, the standard output amplitude of 710
mV
P-P
is used. When this bit is set to 0b, the
reduced output amplitude of 510 mV
P-P
is
used.
POR State: 1b
OE: Output Edge. This bit selects the DCLK
edge with which the data words transition in
the SDR mode and has the same effect as
the OutEdge pin in the normal control mode.
When this bit is 1, the data outputs change
with the rising edge of DCLK+. When this bit
is 0, the data output change with the falling
edge of DCLK+.
POR State: 0b
Must be set to 1b.

Input Offset Value. The input offset of the
ADC is adjusted linearly and monotonically
by the value in this field. 00h provides a
nominal zero offset, while FFh provides a
nominal 45 mV of offset. Thus, each code
step provides 0.176 mV of offset.
POR State: 0000 0000 b
Sign bit. 0b gives positive offset, 1b gives
negative offset.
POR State: 0b
Must be set to 1b
