Rs-170 Buffer for long cable

Hi,

 

We're designing with the ADV7123 Video DAC to implement  RS-170 video signal,

the video signal should drive more then a 10 Meters cable and according to the Datasheet it's recommended to use buffers such as the AD848,

 

Do we need to connect the buffer to a dual supply voltage (negative and positive) to support the RS-170 signal?

Can you recommend on such application?

 

Thanks in advance,

Barak
