Part Number: ADS1274 Hi, I'm working with a ADS1274EVM board in mode FS and a DSK6455 processor. Now I'm developing a board based on the 6745 processor, but I need that the ADS1274 /8 works in SPI mode, and I don´t undestand well how it works. The relationships between fMOD, fCLK and fDATA are given in Tables 6, 3 and 8. Then, if I use fCLK 27 MHz, fDATA = 52734 KHz (HR mode), but my I don´t undestand this: - Is fSCLK = fDATA? - On page 30 (datasheet), SPI interface description, second column, I can read "SCLK may be run as fast as the CLK frequency." How is possible fSCLK = fCLK? What happens with the relationships mentioned above? - Can I use 27 MHz on CLK pin ( ADS1274 ) and generate SCLK signal from 6745 processor? Is it not need any synchronization between those signals? On the DSK6455-ADS1274EVM, the 27 MHz is redirected to the processor for synchronization. Regards.
