All parameters are guaranteed over the virtual junction temperature range by design, but only 100 % are tested at 125 C for dies on
wafer level (pre-testing) and above this for cased products 100 % are tested at T
specified. Both pre-testing and final testing use correlated test conditions to cover the specified temperature and power supply voltage
range. For bare dies all parameters are only guaranteed with the backside of the bare die connected to ground.

Rise and fall time (10 % to 90 %) of t
The worst case asymmetry from one branch to another is the sum of the delay difference from TRXD0 and TRXD1 to DATA_0 and
DATA_1 plus the delay difference from DATA_0 and DATA_1 to TRXD0 and TRXD1.
