Hello Asad,
the CDCM61001 + buffer IC will be a fine solution. You didn't indicate what signaling your inputs require. Is it LVDS, CML, LVPECL, or single-ended?
If it's LVDS , you could use the CDCMVD110: http://focus.ti.com/docs/prod/folders/print…
Hi Surender,
The 1.2-V common mode voltage is part of the LVDS specification, so you aren't likely to find any LVDS devices with such a low common mode. The simplest solution in my opinion is to just use series capacitors to AC-couple the buffer's differential…
