LINEOUT2 single-ended mode is selected by setting LINEOUT2_MODE = 1. In single-ended mode,

any of three possible signal paths may be enabled:



MIXOUTR (right output mixer) to LINEOUT2P



MIXOUTL (left output mixer) to LINEOUT2N



MIXOUTR (right output mixer) to LINEOUT2N

LINEOUT2 differential mode is selected by setting LINEOUT2_MODE = 0. In differential mode, any

of three possible signal paths may be enabled:



MIXOUTR (right output mixer) to LINEOUT2N and LINEOUT2P



IN1L (input PGA) to LINEOUT2P and LINEOUT2P



IN1R (input PGA) to LINEOUT2N and LINEOUT2P

The LINEOUT2 output mixers are controlled as described in Table 54. Care should be taken to avoid

clipping when enabling more than one path to the line output mixers. The LINEOUT2_VOL control

can be used to provide -6dB attenuation when more than one full scale signal is applied.

When using the LINEOUT2 mixers in single-ended mode, a buffered VMID must be enabled. This is

achieved by setting LINEOUT_VMID_BUF_ENA, as described in the “Analogue Outputs” section.
