In the data sheet for the AD6649 the minimum conversion rate is stated as 40 MSPS. Maybe the CLK+ and CLK- inputs are AC coupled to block DC. But I would like the AD6649 CLK inputs to work as low as 30 MHz or lower. I tried using an old function generator with a 1 MHz maximum and that results in missing or corrupt data in Visual Analog. Will the AD6649 just not work at speeds lower than 40 MSPS?
