Forum Post: RE: I need help to read ID and other registers from ADS1291
Can you provide a screen capture of the SPI signals from oscilloscope? Sometimes it is easier to identify problems by looking at the signals.

The 210MHz is above the max. CODEC_CLKIN spec (as you noticed). What do you observe if you set J=10? Is PLL_CLKOUT on GPIO flat (no output) in this case? At what J setting do you get the expected PLL...
