ADC3662: SCLK Frequency - 20MHz or 12MHz?

Jason Haedt

Part Number: ADC3662

In 8.5.2, it says the interface can function with SCLK <=12MHz.

But in the table below it shows it can go to 20MHz:

Which is correct?

    Hi Jason, 

    As you have mentioned, it looks like in the datasheet we have recommended in Section 8.5.2 to run <= 12 MHz, but in the timing requirements table the SCLK maximum is listed at 20 MHz. I will double check to see if this is indeed the case and get back to you. 

    Thanks, Amy

    Hi Jason,

    I confirmed that the maximum is 20 MHz. This is a datasheet error, thanks for catching this.
