Hi EZ team,
My customer is using LTC6409 for driving LTC2208 and need to simulate between these devices including the PCB trace with Keysight ADS. I have tried to find out the Spice models or S-Parameters in ADI web site but can't find out them.
I assume you mean you need DC-56MHz. If this is the case you will need an ADC that samples at least twice 56MHz, or more than 112Msps. Depending on how much filtering you need you will want to sample faster than that. I would recommend the AD9258, a 14…
