eQADC Conversion Speed (SPC563M)

Hi,

in table 298 of SPC563Mx manual are listed conversion speed values given by the formula (see the attachment). The parameters are related to 120 MHz system clock but the mcu can provide 80 MHz clock at maximum. 

I tried to acquire a sine waveform (single-ended mode) generated at 2400 Hz and i set Sampling Cycle to 2 and clock divider to 8. I expected to see 4 periods for 1024 samples but it was acquired only 3 periods (3 and a half at maximum).

What does it mean? Am I wrong in conversion speed calculation? 

P.S.: For single-ended NumberOfADConversionCycles is 14

 

thank you so much. boaser
