28. The digital-to-analog path gain for CODEC1 and CODEC2 is set to 0 dB (CDVC1/2 = 8xH). The DSP is in Idle mode.
The value is differentially measured and psophometrically weighted.
29. The digital-to-analog path gain in control register CDVC1/2 = 8xH is set to 0 dB for CODEC1 and CODEC2, when a
bit stream representing a sinewave of 970 Hz with a level of 0 dBm0 is applied at the PCM interface (DSP output).
The value includes harmonic distortion and is psophometrically weighted. The load between SPKRM and SPKRP or
LIFMOUT and LIFPOUT is 100 pF in parallel to 150
and 800 mH.
30. The digital-to-analog path gain in control register CDVC1/2 = 8xH is set to 0 dB for CODEC1 and CODEC2, when a
bit stream representing a sinewave of 970 Hz with a level of
40 dBm0 is applied at the PCM interface (DSP output).
The value includes harmonic distortion and is psophometrically weighted. The load between SPKRM and SPKRP or
LIFMOUT and LIFPOUT is 100 pF in parallel to 150
and 800 mH.
