16-bit CRC Vs 32-bit CRC

Does anyone know the advantage of using a 16-bit CRC circuitry vs a 32-bit CRC circuitry?

Guys it seams that you forgot one thing.

The quality of the CRC depends on the size of th input.

You can produce a CRC16 for a 32 bits word, 64 bits word and so on....

So it means that in some case the value of the CRC will be the same for 2 differents input values.... In this case, some errors might not be detected.

I hope this help
