LVDS over CAT7 or CAT5 cables

Hello, 

 

I'm wondering what could be the maximal bitrate on I/Os LVDS over 50m CAT7/CAT5 cables (twisted pair). 

Thanks in advance.

I guess less than 50 MBPS without cable equalizer. Did you look at the cable attenuation characteristic? Ethernet 1000BASE-T (250 MBPS per pair) is specified to work over 100 CAT5 with about 24 dB attenuation at highest frequency components. But it accepts a much larger signal dynamic than LVDS.
