TCA9802: Propagation delay on data and clock

The two channels are identical and could be exchanged.

Waveforms are shown in figures 9 and 10.

Figure 9 and 10 show propagation delay between Port A and Port B. 

I’d like to know propagation delay of port A data and port B data, and propagation delay of port A clock and port B clock.

Otherwise, is it the same propagation delay of data and clock when transmission?

Is it possible define the SDA and SCL propagation delay separately?

If SDAA to SDAB propagation delay is 80ns, SCLA to SCLB is 180ns, this would cause I2C hold time decrease.

The application report I²C Dataline Handoff Delay describes the effects of a buffer's propagation delay on the communication. The observed skew between the two channels is zero.
