0x04 7-3
Phase Adjust
These bits provide a phase adjustment for the DLL to
generate the ADC clock. A 5-bit value that adjusts the
sampling phase in 32 steps across one pixel time. Each
step represents an 11.25° shift in sampling phase. The
power up default is 16.
INPUT GAIN
0x05
7-0
Red Channel Gain
These bits control the programmable gain amplifier
(PGA) of the red channel. The AD9880 can accom-
modate input signals with a full-scale range of
between 0.5 V and 1.0 V p-p. Setting the red gain to
255 corresponds to an input range of 1.0 V. A red gain
of 0 establishes an input range of 0.5 V. Note that
increasing red gain results in the picture having less
contrast (the input signal uses fewer of the available
converter codes). The power-up default is 0x80.
0x06
7-0
Green Channel Gain
These bits control the PGA of the green channel. The
AD9880 can accommodate input signals with a full-
scale range of between 0.5 V and 1.0 V p-p. Setting the
green gain to 255 corresponds to an input range of 1.0
V. A green gain of 0 establishes an input range of 0.5 V.
Note that increasing green gain results in the picture
having less contrast (the input signal uses fewer of the
available converter codes). The power-up default is
0x80.
0x07
7-0
Blue Channel Gain
These bits control the PGA of the blue channel. The
AD9880 can accommodate input signals with a full-
scale range of between 0.5 V and 1.0 V p-p. Setting the
blue gain to 255 corresponds to an input range of
1.0 V. A blue gain of 0 establishes an input range of
0.5 V. Note that increasing blue gain results in the
picture having less contrast (the input signal uses
fewer of the available converter codes). The power-up
default is 0x80.
INPUT OFFSET
0x08
7-0
Red Channel Offset Adjust
If clamp feedback is enabled, the 8-bit offset adjust
determines the clamp code. The 8-bit offset adjust is a
twos complement number consisting of 1 sign bit plus
7 bits (0x7F = +127, 0x00 = 0, 0xFF = 1, and 0x80 =
128). For example, if the register is programmed to
130d, then the output code is equal to 130d at the end
of the clamp period. Note that incrementing the offset
register setting by 1 LSB adds 1 LSB of offset,
regardless of the clamp feedback setting.
The power-up default is 0.
0x09
7-0
Red Channel Offset
These eights bits are the red channel offset control.
The offset control shifts the analog input, resulting in
a change in brightness. Note that the function of the
offset register depends on whether clamp feedback is
enabled (Register 0x1C, Bit 7 = 1).
If clamp feedback is disabled, the offset register bits
control the absolute offset added to the channel. The
offset control provides a +127/128 LSBs of adjust-
ment range, with one LSB of offset corresponding to
1 LSB of output code. If clamp feedback is enabled
these bits provide the relative offset (brightness) from
the offset adjust in the previous register. The power-up
default is 0x80.
0x0A
7-0
Green Channel Offset Adjust
If clamp feedback is enabled, the 8-bit offset adjust
determines the clamp code. The 8-bit offset adjust is a
twos complement number consisting of 1 sign bit plus
7 bits (0x7F = +127, 0x00 = 0, 0xFF = 1, and 0x80 =
128). For example, if the register is programmed to
130d, then the output code is equal to 130d at the end
of the clamp period. Note that incrementing the offset
register setting by 1 LSB adds 1 LSB of offset, regard-
less of the clamp feedback setting. The power-up
default is 0.
0x0B
7-0
Green Channel Offset
These eight bits are the green channel offset control.
The offset control shifts the analog input, resulting in
a change in brightness. Note that the function of the
offset register depends on whether clamp feedback is
enabled (Register 0x1C, Bit 7 = 1).
If clamp feedback is disabled, the offset register bits
control the absolute offset added to the channel. The
offset control provides a +127/128 LSBs of adjust-
ment range, with one LSB of offset corresponding to
1 LSB of output code. If clamp feedback is enabled
these bits provide the relative offset (brightness) from
the offset adjust in the previous register. The power-up
default is 0x80.
0x0C
7-0
Blue Channel Offset Adjust
If clamp feedback is enabled, the 8-bit offset adjust
determines the clamp code. The 8-bit offset adjust is a
twos complement number consisting of 1 sign bit plus
7 bits (0x7F = +127, 0x00 = 0, 0xFF = 1, and 0x80 =
128). For example, if the register is programmed to
130d, then the output code is equal to 130d at the end
of the clamp period. Note that incrementing the offset
register setting by 1 LSB adds 1 LSB of offset, regard-
less of the clamp feedback setting. The power-up
default is 0.
