AD9146 quad-witch

Question

Hi 
 I am FAE in Japanese distributor. 
 AD9164 has 4 modes(NRZ,RZ,MIX,2xNRZ). 
 NRZ,RZ and MIX are set by 0x152[1:0]. 
 2xNRZ are set by 0x111[0]. 
 When 2xNRZ(FIR85) is enable, is 0x152[1:0] ignored or the value change the RF signal? 
 Best regards 
 N.Kokubo

Hello, 
 No, output signaling type setting is not ignored when enabling the FIR85 filter. See the "Interpolation Filters" and "Integer NCO Mode" sections of the DS regarding guidance on using the FIR85 filter.
