† _{All typical values are at TA = 25°C.}
‡ _{This is the delay between entering the loopback mode and when the data on the receiver output becomes valid.}
§ _{This is the worst-case (rising or falling edges) total propagation delay between driver input and receiver output when in the loopback mode.}
¶ _{This is the magnitude of the difference between the propagation delay time of the rising and falling edges of tpd(LB).}
NOTE 6: Skew time is the magnitude of the difference between tPHL and tPLH and is measured with a 0-to-3-V input pulse.
