Hi,

Does someone has VHDL code for digital CDR? I'm targetting Altera or Lattice because of the internal PLL (Xilinx only has DLL).
Any help is welcome

Re: CLock Data Recovery
Interestingly, Xilinx have just updated their data recovery app note.

XAPP224 - Data Recovery

I know you're not after Xilinx, but the principles involved should be similar.

Re: CLock Data Recovery
Thanks,

I saw the appication node. It's only the data recovery, not the data extraction. Usually this is the hard part.

So the question is still open..

Regards
