The [[adi>AD9257|AD9257]]/[[adi>AD9637|AD9637]] ADCs can operate in pin mode if there is no need to program and change the default modes of operation via the SPI. For applications that do not require SPI mode operation, the CSB pin is tied to 1.8V_DUT_AVDD by removing any jumper on Pin 8 of J301. In this configuration the SDIO/PDWN pin controls the power-down function, and the SCLK/DFS pin controls the digital output format. | The [[adi>AD9257|AD9257]]/[[adi>AD9637|AD9637]] ADCs can operate in pin mode if there is no need to program and change the default modes of operation via the SPI.
