Simple hardware for Endat 2.2 implementation

Hello,

I recently received an optical encoder from Heidenhain. It works with the Endat 2.2 protocol.

I would like to use this encoder with a dSpace station, using parallel I/O connection.

After some research, I found that the only solution to get angular position on parallel connection is to use an FPGA interface between the encoder and the dSpace station...

My question is : what kind of Altera FPGA board is best-suited only for this application?

Thank you,

Samuel.
