Hi Keith, Thanks so much for all the consultation. I'm just trying to interpret the enhanced SPI requirements- it seems most of them utilize other digital lines. If we go with the 4 wire (/CS, SCLK, SDI, SDO) architecture, is 52 MHz the minimum clock rate needed for 1 MSPS performance? Ideally we would be able to get it a bit lower than this without running another digital line. Thanks again! Ian
