Sending Serial Data from FPGA through Ribbon Cable

[fazan83]

Guys
Is it possible the serial data from the FPGA to the other IC or gate can be loss if we use such a long (1.5Meter) 20AWG ribbon cable?

Please advise.

Thanks in advance.

That depends on many things such as for example speed and noise ..
If you don't need to send much data, lower the speed to, say, 9.6kbps and it should work fine ..

What if I send for example a clock signal at frequency 60Mhz?
Also sending Hsync and Vsync of a RGB signal to the display.

As if I plug this signal straigth away using a connector and it work fine.
But if I use the 1.5m 20AWG ribbon cabble then it will display garbage.

Please advise.

Thanks in advance.

Yes you can. I have done it in the past.

Thanks for your input. How do you fix it?
Understand we can use the connector and plug it straigth away but is there any option on this?
Do we need to arrange the signal-ground-signal-ground if we still want to use the cabel and need to put resistor that match the cables characteristic impedance?
