sweeps from 2.9 V to 4.2 V (DC waveform).
17.2.1
Test 1
S2 = on, S3 = on
DP is terminated using a 200
; DM is terminated using a 60 k
MIC is terminated using a 10 k
; SPKR_L is terminated using a 200
, 1.4 V DC
Drive f = 1 kHz, V
(p-p)
= 1 V to DP; signal on DM must be 66 dB below; where f
represents frequency and V
(p-p)
represents peak-to-peak voltage.
