Hello there! I need to generate a Maximum length binary sequence (MLBS) with an FPGA for a project of mine, which I then have to modulate with a carrier signal. The MLBS needs to be at least 60MHz and above frequency. I found an old Spartan-3 starter kit and started working on it to try and generate such a signal. The problem is that the oscillator frequency of the board itself is just 50MHz. Hence its impossible to generate the requisite signal of 60MHz. There is a plethora of options available here and I am confused as to which will the the most cost effective board that will serve my purpose. I'd appreciate if someone guides me on to the right direction and helps me out in this regard. Regards,

use the internal pll/dll of the fpga to generate 60MHz from the 50MHz

Then I also need to generate a carrier signal of say 200Mhz, modulate my MLBS onto the carrier and then get the resulting signal from an output pin. This seems highly improbable (at least to my weak knowledge) on a Spartan-3 starter Kit.
