DS16EV5110A - Frequency: 2.25Gbps MAX Cable range: 20m

Hi all,

Would you mind if we ask DS16EV5110A?

The datasheet on the P14 shows followings;

"HDMI V1.3 APPLICATION"
"The DS16EV5110A can reliably extend operation to distances greater than 20 meters of 28 AWG HDMI cable at
  2.25 Gbps, thereby supporting HDMI v1.3 for 1080p HDTV resolution with 12-bit color depth. Please note that
  the Electrical Characteristics specified in this document have not been tested for and are not ensured for 2.25
  Gbps operation."

We have some questions about following sentence.
"the Electrical Characteristics specified in this document have not been tested for and are not ensured for 2.25 Gbps operation."

<Question1>
-Is it possbile to ensure for 2.25 Gbps operation in case of 20m AWG28?
-Or does it mean that there is no test data, but it may be ensured for 2.25 Gbps operation using 20m AWG28? 

<Question2>
As like Table6(Setting: 0x06,  Data rate: 2.25 Gbps,  28 AWG DVI / HDMI: 15m to greater than 20m),  
is it possible to use the range from 15m to 20m(within 20m)?

We need your help.

Kind regards,

Hirotaka Matsumoto
