ADRV9009 Image rejection

My customer has the following requirement "The receiver response to spurious signals, including image response, shall be attenuated not less than 80 dB with respect to the received signal."

 The specification for the ADRV9009 is 75db (QEC active within 200MHZ receiver bandwidth) for image rejection.  Is it possible to achieve greater image rejection at lower bandwidths?  Can we achieve spurious performance at this level?

Let me know,
