Tool/software:
Hello!
I'm using the ADS921x family in a design (specifically the ADS9218) operating in single-lane mode. Additionally, our HDL team is using test patterns to calibrate alignment such that FCLK and DCLK are not necessary for all parts in our multi-ADC design, so for some ADS9218 parts we have a number of unused/unconnected pins on the ADC LVDS interface.
My question is -- if there are unconnected DCLK, FCLK, and/or DOUT LVDS pairs on the ADS9218 interface, is there a recommended termination style for them (i.e. 100ohm diff) or can they be left floating without impacting performance?
