Using Fs to 3/2Fs band in P240 board without considerable loss

Hi, I'm using a Virtex 4 board with a P240 module, sampling with 56.25 MSPS.  I'm working from 3.75 MHz to 23.75 MHz in the FPGA. I need  to work  from 60 MHz to 80 MHz at the DAC output Using the P240 module.

I have able to enable this band unenabling P240 FIRs, but I loss around 15 dB in this band,  it seems  that it has a zero in 56.25MHz.

Can I configure P240 DACs in order to minimize this loss? The actual decreases my S/N relation considerably.

I appreciate any help.

Best regards,

Eugenio.
