Can any body forward me some links or some ideas for designing an ideal hardware.

Tell me, if you have found one...

No, dear Sachin, I don't believe that there's any shortcut to real EXPERIENCE, made by yourself. You need 'some' years of experience to find the 'ideal harware'. 'Ideal' here means the 'ideal compromise'. All people doing in harware electronics are making compromises all day long. You can only find the 'ideal' set of compromises for a certain application, but never the 'ideal hardware'.

Some very useful information you will find here

and here

Especially this link here

http://www.murata.com/emc/knowh...8to15e.pdf

is a must for every designer of digital boards.

The best advice I can give you is: Read, read, read, read, read, read, read, read, read,....

Do also read datasheets and application notes about chips you are not especially interested in. Sometimes, the gain of knowledge can be quite enormous then!
Don't forget that authors of technical informations will fail from time to time. Then, only by cross reading of similar papers you will find the 'truth'. Do never trust only one source.

Which automatically results in the recommendation: Read, read, read, read, ....

Good luck,
Kai
