I wnated to know if there are any further information about the reconstruction filter used on the Ad9958/9959 Evaluation Board?

Am i right that it is a 200 MHz low pass elliptic filter, 7th order?

What is the stopband width and depth? Stopband depth should be at least 65 dB (Technical Tutorial on Direct Digital Synthesis)?


Thanks in regard
