1) TA depends on the clock source selected for baud rate generation in the ABRA block of the MSC.
2) The capacitive load on the LVDS pins is differential, the capacitive load on the CMOS pins is single ended.
3) The load (CL=50pF) defined in the condition list is a load definition for the single end signal EN and does not intend to add an
additional load inside the differential signal lines. For single end signals the load definition defines the max length of the signal
on the PCB layout. For the LVDS pads the IEEE Std 1596.3-1996 load definitions apply.
