Venkateshwarlu look at using a zero delay clock buffer from Cypress, the http://www.cypress.com/cfuploads/img/products/38-07140.pdf is a good example. This guarantees that good distribution with no delay in the clock path, one clock in many clocks out.

Subject: Buffer on clock signal
** Proprietary **
Hi all,
I use MPC8245 for my design, acts as PCI host. 5 clock signals are there for 8245, 4 out of these 5 are multiplexed with UART signals. I need 4 PCI clocks for 4 pci agents, and also UART chips. Iam planning to take one clock signal, buffer it and get 4 out of this one clock signal. Is it ok, or does it create any timing problems.
Looking forward for ur reply.
