Data Rate Control Register
The Data Rate Control register controls the output data
period, which corresponds to the output data rate of
the ADC. The data period is controlled by both a
coarse (FSAMPC[2:0]) and a fine (FSAMPF[10:0])
adjustment (see Table 8).
The final data rate is derived by dividing the XIN clock
frequency by a divider value. The divider value is a
function of FSAMPC[2:0] and FSAMPF[10:0]:
Data Rate = fXINCLOCK/Divider
Divider = Coarse Cycle Factor x 384 + Fine Cycle
Factor x FSAMPF[10:0]
Note: Fractional results for the divider are rounded
down to the nearest integer. Coarse cycle factor and
fine cycle factor come from Table 8. The effect of
FSAMPF[10:0] in the formula has limitations as noted in
the table.
Examples of output data rate vs. FSAMPC[2:0] and
FSAMPF[10:0] are shown in Table 9. Table 10 shows
typical device performance for various data rate settings.
