ADC3664: Clock Frequency?

Part Number: ADC3664

Hi Team,

Can you please check and advise with following request?


On page 7 of the product's data sheet, 0.5 MHz is specified as the minimum value of "Input clock frequency" if "External reference" is used;

However, on page 20, there is a phrase "External Reference: 65 to 125 MSPS",

which one is the valid information?


Thanks in advance

Best Regards

Furkan Sefiloglu

  • Hi Furkan,

    The ADC3664 can sample all the way down to 0.5 MSPS, but datasheet specs are not guaranteed across temperature and other variations below 65 MSPS (with external voltage reference).
