Hi guys.


I have two questions regarding PCA9507, I2C bus extender. 

Accoding to datasheet, distance, using this IC, is limited 1400pF or 18m on port A. 

My questions now are:

   1. Is this limit, 18m, having PCA9507 on one side only or it has to be on both sides, if we talk about point-to-point?

   2. If I have PCA9507 on both sides, is it OK to have port A towards each other, since there are rise time accelerators?


I am asking this since our board has HDMI input and output ports.


Thank you for your answers. 


Enjoy the rest of the weekend.
