n8/n12
These test points are outputs of Op-Amp that make differential output of D/A converter into single end output.
The reference GND is TL260 (AGND).
6. Checking audio synchronized clock
TL104 (128FS)
Clock with frequency 128-fold of sampling frequency and signal amplitude of 3.3 V.
If the clock is not normal, it is not possible to input/output audio signals at SSP1 (IC107, IC110).
The clock is provided by the MLAN circuit board and provided directly to SSP1 from 100-pin connector (CN109).
* TL104 is after passing buffer IC (IC118) and correct judgment is not expected if the IC118 output is damaged.
The reference GND is TL258 (DGND).
TL253 (256FS)
Clock with frequency 256-fold of sampling frequency and signal amplitude of 3.3 V.
If the clock is not normal, A/D converter and D/A converter will not work normally.
The clock is supplied by the MLAN circuit board and provided to A/D converter and D/A converter from the 100-pin connector
(CN109) through IC118.
The reference GND is TL258 (DGND).
TL254 (64FS)
Clock with frequency 64-fold of sampling frequency and signal amplitude of 3.3 V.
If the clock is not normal, A/D converter and D/A converter will not work normally.
The clock is supplied by the MLAN circuit board and provided to A/D converter and D/A converter from the 100-pin connector
(CN109) through IC118.
The reference GND is TL258 (DGND).
TL255 (WCK)
Clock with the same frequency as the sampling frequency and signal amplitude of 3.3 V.
If the clock is not normal, audio input/output at SSP1, A/D converter and D/A converter will not work normally.
