Left and Right DAC Input Mixer (MIXDAL/MIXDAR)
Table 16 shows the possible mixing configurations of
the incoming digital audio streams. Each of the four
digital audio streams can be mixed in any combination
and routed to the left or right DAC independently.

Transducer/Vibe DAC Output Select (TMUX)
00 = VIBE is high.
01 = VIBE is low.
10 = Inverted threshold comparator output connected
to VIBE.
11 = Inverted 1-bit DAC nonfiltered output connected
to VIBE.
See the VIBE Output section. TMUX selects the signal
path of the VIBE output. Set TSEL (register 0x07, B5).
Transducer/Vibe DAC Path Enable (TSEL)
1 = Secondary (S2) left or left + right digital audio signal.
0 = Primary (S1) right digital audio signal.
TSEL = 0 configures the MAX9851/MAX9853 to use the
right channel of the primary digital audio interface for
transducer/vibe signal conditioning. TSEL = 1 configures
the MAX9851/MAX9853 to use the left channel (or left +
right if S2 mono mix is enabled) of the secondary digital
audio interface for transducer/vibe signal conditioning.
Transducer/Vibe Squelch Comparator Threshold
(VTH)
When using the comparator for VIBE output, program
VTH to set the level that positive digital audio data will be
compared against. If the input data is less than VTH, then
VIBE = 1. If the input data is greater than VTH, then VIBE
= 0. If VTH = 0x00, all negative signal values will force
VIBE high and all positive values will force VIBE low (see
Figure 6 for operation).

X = Don’t care.
