AD9910 Datasheet Version: Rev C,Link:http://www.analog.com/static/imported-files/data_sheets/AD9910.pdf

Info1:Page50 CFR3 Control function Register 3(0x02) 31:24 default value:0x1F,this mean DRV0[1:0] = 01b,DRV0[0] = 1.

Info2:Page58 Table 20. Bits description for CFR3 DRV0 "Controls the REFCLK_OUT pin(see Table 7 for details); default is 00b".

 

My test:

Power on the DDS's all power voltage. Then let the DVDD 3.3V open, REFCLK_OUT pin output the XTAL clock.

Result:

"Info1:Page50 CFR3 Control function Register 3(0x02) 31:24 default value:0x1F,this mean DRV0[1:0] = 01b,DRV0[0] = 1" is wrong.

?
