PRODUCTION DATA.
The MUTELVL1 register determines the Output Driver during mute for output drivers 0 to 3.
| Bit # | Field | Type | Reset | EEPROM | Description | ||
|---|---|---|---|---|---|---|---|
| [7:6] | CH3_MUTE_LVL[1:0] | RW | 0x1 | Y | Channel 3 Output Driver Mute Level. CH3_MUTE_LVL determines the configuration of the CH3 Output Driver during mute as shown in the following table and is recommended to be set to 0x3. CH3_MUTE_LVL does not determine whether the CH3 driver is muted or not, instead this is determined by the CH_3_MUTE register bit. | ||
| CH3_MUTE_LVL | DIFF MODE | CMOS MODE | |||||
| 0 (0x0) | CH3 Mute Bypass | CH3 Mute Bypass | |||||
| 1 (0x1) | Powerdown, output goes to Vcm | Out_P Normal Operation, Out_N Force Output Low | |||||
| 2 (0x2) | Force output High | Out_P Force Output Low, Out_N Normal Operation | |||||
| 3 (0x3) | Force the positive output node to the internal regulator output voltage rail (when AC coupled to load) and the negative output node to the GND rail | Out_P Force Output Low, Out_N Force Output Low | |||||
| [5:4] | CH2_MUTE_LVL[1:0] | RW | 0x1 | Y | Channel 2 Output Driver Mute Level. CH2_MUTE_LVL determines the configuration of the CH2 Output Driver during mute as shown in the following table and is recommended to be set to 0x3. CH2_MUTE_LVL does not determine whether the CH2 driver is muted or not, instead this is determined by the CH_2_MUTE register bit. | ||

| [3:2] | CH1_MUTE_LVL[1:0] | RW | 0x1 | Y | Channel 1 Output Driver Mute Level. CH1_MUTE_LVL determines the configuration of the CH1 Output Driver during mute as shown in the following table and is recommended to be set to 0x3. CH1_MUTE_LVL does not determine whether the CH1 driver is muted or not, instead this is determined by the CH_1_MUTE register bit. | ||

CH0_MUTE_LVL determines the configuration of the CH0 Output Driver during mute as shown in the following table and is recommended to be set to 0x3. CH0_MUTE_LVL does not determine whether the CH0 driver is muted or not, instead this is determined by the CH_0_MUTE register bit. | ||
