Can minimum conversion rate of AD9642-250 be 800KSPS? is there any data converter(conversion rate is from 800ksps to 250Msps)?
The minimum sample rate for the AD9642-250 is 40Msps. It won't operate at a sample rate of 800kHz.
The LTC2242 has a minimum sample rate of 1Msps, so 800kHz would probably work.
Why the need for such a wide range of sample rates? We typically don't recommend changing the sample rates in a system that drastically. It is easier to sample at the fastest rate possible and decimate to a slower sample rate in an FPGA.
Thank you very much,
