4.11 High-Power Outputs Tab
Figure 27. High-Power Outputs Tab
The High-Power Outputs tab contains horizontal groupings of controls, one for each one of the high power
outputs. Each output has a mixer to mix the PGA_L, PGA_R, and DAC_L signals, assuming that the
DACs are not routed directly to the high power outputs. The High-Power Outputs tab is shown in
At the left of each output strip is a
Powered Up
button that controls whether the corresponding output is
powered up or not. The
When powered down
button allows the outputs to be tri-stated or driven weakly
to the output common mode voltage.
The HPCOM output can be used as an independent output channel or can be used as a complementary
signal to the HPOUT output. In these complementary configurations, the HPCOM output can be selected
as
Differential of HPOUT
signal to the HPOUT output or may be set to be a common mode voltage
(
Constant VCM Out
). When used in these configurations, the
Powered Up
button for the HPCOM output
is disabled, as the power mode for that output will track the power status of the HPOUT output. The
selection of
Differential of HPLCOM
or
Ext. Feedback/HPLCOM constant VCM
should not be selected for
the TLV320AIC3109EVM evaluation.
At the right side of the output strip is a master volume knob for that output, which allows the output
amplifier gain to be muted or set from 0 to 9 dB in 1-dB steps.
4.12 Preset Configurations Tab
The Preset Configurations tab should be ignored for the evaluation of the TLV320AIC3109-Q1 as the
configuration used in that tab is relevant for the TLV320AIC3104 device only. Scripts for the correct
configuration of the TLV320AIC3109EVM are included in
. These scripts can be loaded into
the EVM by using the
Command Line Interface
tab, shown in
