Am developing a board using AD9211 interfaced with Virtex-5 FPGA. Outputs of the ADC are at LVDS 1.8V and these outputs have to be given to an FPGA bank working at 2.5V. Are these outputs compatible with FPGA 2.5V ?
I moved this question to the High-Speed ADCs community. Please continue the discussion here.

The output swing of these are compatible, but the common mode voltage voltage may be different. If the common mode of the receiver lines up with the AD9211, then you can use them directly. If the common mode of the receiver is higher, you will need to ac couple the outputs to the receiver. I believe that most receivers will be directly compatible.
