AD9981
TWO-WIRE SERIAL REGISTER MAP
The AD9981 is initialized and controlled by a set of registers, which determine the operating modes. An external controller is employed to
write and read the control registers through the two-wire serial interface port.

Description
An 8-bit register that represents the silicon revision level.
This register is for bits [11:4] of the PLL divider. Larger values
mean the PLL operates at a faster rate. This register should be
loaded first whenever a change is needed. (This will give the PLL
more time to lock.)
1
Bits [7:4] LSBs of the PLL Divider Word. Links to the PLL Div MSB
to make a 12-bit register.
1
Bits [7:6] VCO Range. Selects VCO frequency range.
(See PLL description).
Bits [5:3] Charge Pump Current. Varies the current that drives the
low-pass filter. (See PLL description).
Bit 2. External Clock Enable.
ADC Clock Phase Adjustment. Larger values mean more delay.
(1 LSB = T/32).
7-Bit Red Channel Gain Control. Controls ADC input range
(contrast) of each respective channel. Bigger values give less
contrast.
Linked with Register 0x05 to form the 9-bit red gain that controls
the ADC input range (contrast) of the red channel. A lower value
corresponds to a higher gain.
1
7-Bit Green Channel Gain Control. Controls ADC input range
(contrast) of each respective channel. Bigger values give less
contrast.
Linked to Register 0x07 to form the 9-bit green gain that controls
the ADC input range (contrast) of the green channel. A lower
value corresponds to a higher gain.
1
7-Bit Blue Channel Gain Control. Controls ADC input range
(contrast) of each respective channel. Bigger values give less
contrast.
Linked to Register 0x09 to form the 9-bit blue gain that controls
the ADC input range (contrast) of the blue channel. A lower value
corresponds to a higher gain.
1
8-Bit MSBs of the Red Channel Offset Control. Controls dc offset
(brightness) of each respective channel. Bigger values decrease
brightness.
1
Linked to Register 0x0B to form the 11-bit red offset that controls
the dc offset (brightness) of the red channel in auto-offset mode.
8-Bit MSBs of the Green Channel Offset Control. Controls dc
offset (brightness) of each respective channel. Bigger values
decrease brightness.
1
Linked to Register 0x0D to form the 11-bit green offset that
controls the dc offset (brightness) of the green channel in auto-
offset mode.
8-Bit MSBs of the Red Channel Offset Control. Controls dc offset
(brightness) of each respective channel. Bigger values decrease
brightness.
1
Linked to Register 0x0F to form the 11-bit blue offset which
controls the dc offset (brightness) of the blue channel in auto-
offset mode.
