LogiCORE IP Asynchronous Sample Rate Converter (ASRC) - Why do I see variation or "glitches" on the output when my input is a DC value?

Description

Why do I see variation or "glitches" on the output when my input is a DC value?

Solution

Small variations are considered part the pass-band ripple.

Also,this could possibly be an overflow in the XAPP1014 Asynchronous Sample Rate Converter example designs for Virtex-5 devices.
The overflow problem has been resolved in the Asynchronous Sample Rate Converter v1.0 core.
