Dear all,
I am trying to use differential LVPECL interface on Xilinx virtex-II pro device.
I have to connect some standard LVPECL(3.3V) signal to virtex-II pro device. But I know that Virtex-II Pro devices support only LVDS_25 and LVPECL_25. There is no problem with Spartan-IIE or Virtex-II device because they have a LVPECL_33 I/O.
I want to know how I connect between standard LVPECL(3.3V) signal and virtex-II pro LVPECL_25 signal in differential manner.
Could anybody give me some answer ?
Thanks, james.
