DS100MB201: new MUX requirement for 10G and 25G serdes

HI team,

My customer has a new requirement below.

MUX (with or without retimer function is fine)

1) transition between channel 2 and channel 3. The transition time within 50ms.

2)the serdes speed 10G or 25G.

How about DS100MB201 and  DS250DF230 here? Do you have other recommendations?

Thanks.
