FPGA family selection (novice) problem.

Hello, I'm new to the FPGA devices (up to now I have done only a few simple project on the CPLDs). I have to design a bandpass FIR filter which will be working with a 16bit ADC, at 100MHz o...

From what you have described so far, you should be able to satisfy your needs with a Cyclone III part. This would be your least expensive option at the moment. As far as what to take care of ... There are a lot of caveats that might get you in trouble. Too many to cover in a forum post.

Initially, you need to make sure you select a large enough device to fit your logic into. If in doubt, get a larger part than what you think you need.

Aside from that. Read the user guide for the FPGA that you select. Do not try to design a PCB without reading the user guide. As you are connecting the FPGA pins on your schematic, refer to the user guide for the functionality of each pin and how it should be connected. Many forum posts are a result of people failing to read the documentation.
