50 ohm termination & level conversation

Dear All,

I have 2 questions to you

a) I have FPGA processing some video Info and i have design circuit to feed the video info into 50 ohm cable. The 50 ohm connector would fixed to my PCB and mating connector of 50 ohm would be connected to drive for 10 mtrs. kindly suggest some sample circuits

b) I have video signal of -2v and i need to convert this -2v to +2v and feed through the connector said above.

with regards
Manju

Seems that you need a video amplifier.

Video amplifier 2

Hi Manju,
I should also point out to you that 75 Ohm is the standard for a video signal, and any impedance matching amplifiers etc should reflect that fact. And although it doesnt state it, I would suspect that that video amp that vfone has linked to for you would be matched for that impedance. :)
