HD3SS215: BW of single ended interface

HI,

thanks for replay!! I have two options for the single ended signals:

1. as you said, one signal for each diff channel - I will use as you recommended the negative with pulldown in that case. what will be the BW of the signal in this case (diff will be 7GHz)?

2. you two single ended signal on each channel (one on the positive and one on the negative). what willbe the performance here?>

In general, I want to use 3 devices for the following signals to mux: 10xdiff with BW of 2.5GHz and 7 signals single ended with BW of 625MHz.

I thought the following: 

device A: 4 diff pairs on Dx ports, 2 S.E in aux+ and aux- ports.

device B: 4 diff pairs on Dx ports, 2 S.E in aux+ and aux- ports.

device C: 2 diff pairs on Dx ports, and the last 3 S.E in the remaining Dx ports or Aux + Dx.

can aux be also used as 2 Single ended signals or better to use as one and the other in pull down? what is the best way to switch the 7 S.E. signals with those 3 devices (after using 10 ports with high BW diff pair)?

thanks for the advice!!!!

no problem.

so, do you think its better for my application to use a device like TS3DDR4000 ?

this way i will need 2 devices for the diff pairs, and i will have 4 ports remaining that can be used for the single ended. I just need to find small solution for the left 3 single ended signals.
