Unsatisfactory.
Neglecting the digital anti-imaging filter makes the discrepancy. You must take into account your digital filter twice.
I attached the slides I made during my visit for March LVC '09. P.5 would be useful.

Result:
[time delay of the CDS] (left, middle)
The time delay gets larger with frequency. The time delay seems to be -175 usec at DC.
However, the gain seems a little different from my expectation(feCoeff4x). So, there are maybe other filters I don't know.
I neglected TF of upsampling this time.
