SW2 = on and SW3 = on.
DP is terminated using a 200
MIC is terminated using a 10 k resistor, and SPKR_L is terminated using a 200
resistor, 1.4 V DC.
Drive f = 1 kHz, V = 1 V (p-p) to DP; signal on DM must be 66 dB below.
SW1 = on and SW3 = on.
DP and DM are terminated using a 60 k resistor.
SPKR_L and SPKR_R are terminated using a 200
Drive f = 1 kHz, V = 1 V (p-p) to SPKR_R; signal on DM must be 66 dB below.

SPKR_L and SPKR_R terminated using a 200
Drive f = 1 kHz, V = 1 V (p-p) to SPKR_L; signal on DP must be 66 dB below.
V
12 Mbit/s USB data is to be active on the DP and DM pins.
All audio switches must be left open.
MIC must be terminated using a 10 k resistor.
SPKR_L and SPKR_R are each to be terminated using a 200
Taking an FFT on the SPKR_R/MIC and SPKR_L pins, USB data components below
20 kHz will be < 70 dB below the USB data level (3.6 V).
