Notes to the characteristics
1.
The oscillator is designed to operate together with a MURATA resonator CSB503F58 for TDA9855. Change of the
resonator supplier is possible, but the resonator specification must be close to CSB503F58 for TDA9855.
2.
The internal SAP carrier level is determined by the composite input level and the level adjustment gain.
3.
Select in to input line control.
4.
Crosstalk:
5.
The transmission contains:
a) Total initialization with MAD and SAD for volume and 11 DATA words, see also definition of characteristics
b) Clock frequency = 50 kHz
c) Repetition burst rate = 400 Hz
d) Maximum bus signal amplitude = 5 V (p-p).
The listed pin voltage corresponds with typical gain steps of +6 dB, +3 dB, 0 dB,
6 dB and
15 dB.

decay time results in 4.14 s.
When reset is active the GMU-bit (general mute) and the LMU-bit (LINE OUT mute) is set and the I
