ADAU1442/ADAU1445 ASRC performance

Is any performance or implementation data available for the ASRCs on these SigmaDSP parts such as THD, DNR, or FIR taps/group delay?  If not, I notice the supported ratios match the AD1895/AD1896---is it reasonable to use, say, the AD1895 as a proxy?  Since the SPDIF receiver must be routed through an ASRC I'm also curious how performance of ADAU144x SPDIF receive compares with parts such as the WM8804 or CS8416.

 

Obviously, I can build a few proto boards and measure these configurations.  But I wanted to check to make sure I'd not be reinventing the wheel first.
