SN65LVDS047: Regarding tsk(lim)

Hi support team.

I am asked regarding the specification of tsk(lim) from my customer.

Note on datasheet "tSK(lim) is defined as |Min - Max| differential propagation delay."

-> Maximum tsk(lim) is 1.2ns on the datasheet. 

    My understanding is that |Min - Max| is |tphl_min - tphl_max| = | 1.4ns - 2.8ns | = 1.4ns, is this correct? 

    If incorrect, how do I think about it?

Thanks and Best regards,

Higa
