ADS7054: SPI Clock driven at 25MHz?

Part Number: ADS7054

Hi team,

My customers are interested in driving this part at 25MHz (their lab equipment allows for either 12.5Mhz or 25MHz).

What would happen if the SPI clock was driven at 25MHz? This would only be done for testing purposes, not in the production environment.

Thanks,

Lauren

    Hi Lauren,

    The SCLK on the ADS7054 is MAX 41.66nS or 24.003MHz.  Running at 25MHz should still work, but we could not guarantee the conversion results would meet the specifications listed in the data sheet.
