USB2517: USB Line termination

Hello,
 
I'm using the USB2517 to design a USB hub,  is the termination for full or high speed required and is the capacitors filter needed, and do we need a driver output impedance of around 27 ohms for 90ohm parallel impedance. 
 
Thanks,
Dino

    Briefly looking at the product page it says the termination and pullup/pulldown resistors are fully integrated.  So you should be ok for the hub side.  If you have any questions let me know.

    It's all in the chip, don't add anything extra on the upstream side.
