In the default mode of operation, the data rate at the output of the ADS5294 is at the sampling rate of the ADC which is true even when the custom pattern generator is enabled. In addition, both output data rate and sampling rate can be configured to a sub-multiple of the input clock rate.
With the DATA_RATE<1:0> control, the output data rate is programmed to be a sub-multiple of the ADC sampling rate. This feature is used to lower the output data rate, for example, when the decimation filter is used. Without enabling the decimation filter, the sub-multiple ADC sampling rate feature is used.
The different settings are listed in Table 10.
DATA_RATE<1> | DATA_RATE<0> | OUTPUT DATA RATE |
---|---|---|
0 | 0 | Same as ADC sampling rate |
0 | 1 | 1 / 2 of ADC sampling rate |
1 | 0 | 1 / 4 of ADC sampling rate |
1 | 1 | 1 / 8 of ADC sampling rate |
