Table 3 ADC clock frequencies and sample frequencies based upon using the APLL as a clock source
Note
1. By using the APLL as a clock source 12 sample frequencies will be reported to the USB host.
Table 4 ADC clock frequencies and sample frequencies based upon using the OSCAD as a clock source
Notes
1. By using the OSCAD as a clock source, the sample frequency and the Q dividing factor must be filled in the
2. The oscillator frequency (and therefore the crystal) of OSCAD must be between 8.192 and 14.08 MHz.
3. The Q factor can be 1, 2, 4 or 8.
4. Sample frequencies below 5 kHz and above 55 kHz are not supported.
