Inter-channel Crosstalk: LINE_IN_L – LINE_IN_R
Figure 3 shows a cross talk measurement for Left to
Right channel for LINE_IN signals. The LINE_IN_L input
is driven by a 2Vrms source. Both AC97 LINE signals
are loaded by 10KΩ resistors and pins 5,7 and 22 on the
device are grounded. Crosstalk from
AC97LINE_IN_L to AC97LINE_IN_R, measured over the
audio band of 20Hz to 20KHz, is in excess of –90 dB.
