Headset Voice Call:
Tx Voice and Rx Voice Separation
1kHz full scale differential input on
RXP/RXN via RXVOICE to LOMIX
and ROMIX, output to LOUT and
ROUT; Quiescent input on LIN12
or RIN12 (Gain=+12dB),
differential output to LOP/LON or
ROP/RON; Measure crosstalk at
LOP/LON or ROP/RON output
Stereo Line Record and Playback:
DAC/Headset to ADC Separation
-5dBFS input to DACs, playback
to LOUT and ROUT1; ADC record
from line input; Measure crosstalk
on ADC output
