Nagammai,
There have been a few posts recommending approaches for designing your input
circuit. If you don't have access to the circuit at that level (e.g. you're
interfacing to an existing piece of equipment), then there are two other
options:
1) AC-couple into one of the inputs (only if your duty cycle is near 50%)
2) Use an external device to convert the signal to differential
We have two products that do the latter, either our dual channel PECL
receiver/line driver:

or our 1:2 PECL fanout buffer, which can also take single-ended inputs:

Both are available in PECL, NECL and LVPECL versions. HTH!
