Programming the AD9850 Serially

Question asked by CurtCarpenter on Jul 15, 2012
Latest reply on Jul 16, 2012 by CurtCarpenter

This may be a foolish question and if so I apologize in advance, but when I shift my 40-bit control data into the AD9850 bit-by-bit in the serial programming mode, which bit do I send first,  W0 or W39?  I haven't been able to spot a clear answer in the data sheet -- although it may be there and I'm just not seeing it.

 

Any help appreciated.
