Hi Hooman.
Thank you for your feedback.
I made changes suggested by you.Now i am able see some pulses on CLKOUT pin and i captured some images from oscilloscope and same is shown bellow.
Am observing some noise on the CLKOUT pin (fig 1).
When i expand the time base ie shown in fig2.
Frequency and period details are shown in right bottom corner of each image.
Regards
