AFE7444EVM: AFE7444EVM

Part Number: AFE7444EVM

Hi,

I noticed the SPI clock in the AFE7444EVM is around 30kHz. 

can you tell me the process to increase it like 40 MHz. to its maximum speed.

With rggards,

  • Hi Ganesh,

    On the AFE7444EEVM, SPI clock speed is limited by the USB (FTDI) device protocol being used. It is not possible to increase the SCLK frequency to 40Mhz using EVM USB interface. Jumpers JP13 can be used to connect SPI bus to FMC (or tap out and be connected to external SPI driver).
