XXX0 0001
−12 dB nominal; implemented for flexibility
reasons. With this setting, the adaptation to
different standard requirements can be done.
XXX0 0010
−6 dB nominal; implemented for flexibility
reasons. With this setting, the adaptation to
different standard requirements can be done.
XXX0 0100
Nominal setting; typical output level is
55 mV (RMS) for PC / SC ratio of 13 dB
(see Section 12, SSIF/mono sound output).
XXX0 1000
+6 dB nominal; implemented for flexibility
reasons. With this setting, the adaptation to
different standard requirements can be done.
XXX1 0000
+12 dB nominal; implemented for flexibility
reasons. With this setting, the adaptation to
different standard requirements can be done.
XXXX XXXX don’t care if mono sound output is chosen
(SSIF_SND[1:0] = 01)
Remark: The SSIF level depends also on the used capacitor C_S. Please refer to
