Re: ADSP-TS101 Booting Option
Dear Analog Team, We are using Spansion S29AL016J55TFNR10, 16Mbit NOR flash for booting the ADSP-TS101. When NOR flash is driving the data to the processor has 12.8ns of rise time, Even though the...

Hi, still having trouble with AD7606? ;-) Connecting CONVSTA/B and SCLK to the same pins of the µC is ok, as they are inputs of the AD7606. No problem to drive them in parallel. Connecting DOUTA/B of...

You are correct in your interpretation of how the SHARC works. It is not a byte-addressable architecture, and all data elements are treated as 32-bit entities. From the SPI perspective on the SHARC...

Hi Klaus, Having made the above adjustment, I can now see all values being clocked out onto the MISO line. I have another issue now though, which is that the data does not appear to be aligned with the...

When you change the CPHASE to 1 you would also have to change CLKPL from 1 to 0 so that your driving edge stays the same and keep proper setup and hold requirements. However,judging from the scope...
