Hello I´m using the crystal oscillator of the ADS1262EVM and its nominal frequency is 7.3728 MHz. I have measured the /DRDY pin with the oscilloscope and its response is correct and correspond with the programming data rate. But I have seen three cases: 1.- For low frequencies the /DRDY pin show perfect and the data is retrieval (as it is said in the pag. 67 of datasheet). All work good. 2.- When the frequency is increased for example to 7200 SPS, the data is not retrieval. I would like to know why happens this and how I can put a solution. 3.- When I use a frequency of 100 SPS for example and I measure the time with a timer, I obten an incorrect value of time that correspond with a samplig rate to 400 SPS. But at the same time, the signal of /DRDY pin measured with the oscilloscope is correct and correspond with the 100 SPS. Why happen this if in the code I´m using the "while" to wait until the data is ready? Thank you Best regards.
