Additional test conditions: AUD_DIV[n] = 00001100; input signal 1 kHz, 90 mV (RMS); AUD_IN_ENA = 1.
Coding system for ADC output data is 2’s complement.
See Fig. 35.
Additional test conditions: AUD_DIV[n] = 00001100; 0 dB output attenuation; 90 % of digital full scale input voltage;
16
speaker connected.
Additional test conditions: TEL_DIV[n] = 0101000; 0 dB output attenuation; 90 % of digital full scale input voltage;
1200
load.
Coding system for DAC input data is 2’s complement.
See Fig. 36.
Additional test conditions: TEL_DIV[n] = 0101000; input signal 1 kHz, 300 mV (RMS); TEL_IN_ENA = 1;
TEL_VOICE_ENA = 0.
See Fig. 37.
See Fig. 38.
10. Deviation of the analog output from 0, with 0 code input to telecom output path.
11. The ADC cannot be started or armed if the touch screen circuit is set to interrupt mode (TSC_MODE[n] = 0,0).
12. Coding system for ADC is binary offset.
13. This is a requirement when an odd divisor is set in either the audio or the telecom codec.
14. This is valid for all SIB frame bits 0 to 63, except bits 17 to 20.
15. This is valid for a the SIB frame bits 17 to 20.
16. All curves repeat around the sample frequency f
sa
or f
st
for audio- respectively telecom codec.
17. Any touch-screen resistor above the maximum will not reach full scale and not saturate the ADC
18. The threshold can be used to verify a valid touch using pressure measurement.
