DCS_DAC_WR_

VAL_1 [7:0]

0000_0000

Writing to this field sets the DC Offset value for HPOUT1R in DAC Write DC

Servo mode.

Reading this field gives the current DC Offset value for HPOUT1R.

Two’s complement format.

LSB is 0.25mV.

Range is -32mV to +31.75mV

7:0

DCS_DAC_WR_

VAL_0 [7:0]

0000_0000

Writing to this field sets the DC Offset value for HPOUT1L in DAC Write DC

Servo mode.

Reading this field gives the current DC Offset value for HPOUT1L.

Two’s complement format.

LSB is 0.25mV.

Range is -32mV to +31.75mV

HPOUT1_ATTN

HPOUT1L and HPOUT1R Attenuation

0 = 0dB

1 = -3dB

Note that, when CP_DYN_PWR=0, then any update to HPOUT1_ATTN is

not fully implemented until a ‘1’ is written to HPOUT1_VU.

HPOUT1L_RMV_

SHORT

Removes HPOUT1L short

0 = HPOUT1L short enabled

1 = HPOUT1L short removed

For normal operation, this bit should be set as the final step of the HPOUT1L

Enable sequence.

HPOUT1L_OUTP

Enables HPOUT1L output stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after the DC offset

cancellation has been scheduled.

HPOUT1L_DLY

Enables HPOUT1L intermediate stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after the output signal path

has been configured, and before DC offset cancellation is scheduled. This bit

should be set with at least 20us delay after HPOUT1L_ENA.

HPOUT1R_RMV_

SHORT

Removes HPOUT1R short

0 = HPOUT1R short enabled

1 = HPOUT1R short removed

For normal operation, this bit should be set as the final step of the HPOUT1R

Enable sequence.

HPOUT1R_OUTP

Enables HPOUT1R output stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after the DC offset

cancellation has been scheduled.
