AD9689 PN9 and PN23

Ok, I think the issue was that I was assuming that the LFSR was the random number itself. The idea is to get the last bit of fourteen consecutive LFSRegisters, and tie them together into a 14-bit word, right?

All right, I have managed to create a C++ code to reproduce these numbers.

Here is what I get por PN9 (notice that the seed given in the manual is big endian, so you need to swap it, but it does not make any difference):
125b 3c9a 2660 c65 697 3d16 eb2 33c7 3741 2b6e 305a 3eaa 14a 3cbb 2073 293d 1d44 219c bdb d0e 3c3f 383d 3c5c 3209 13b4 1e7c 362a 11c6 3571 c44 84 184e 1561 2f4d 3228 15a7

which matches quite well the manual, table 39. However, when I measure, I see totally different sequence (decimal):

3492, 9061, 14751, 5018, 6504, 8937, 4429, 11320, 10430, 13457, 12197, 8533, 7861, 9028, 16268, 14018, 699, 15971, 5156, 4849, 9152, 10178, 9123, 11766, 3147, 387, 10709, 3641, 10894, 5051, 8059, 1969, 2718, 12466, 11735, 2648, 9435, 12806, 4787, 12263, 11634, 5125, 5346, 1688, 15377, 16169, 10399, 12930, 2813, 14982, 575, 9773, 325, 15804, 4584, 12901, 6279, 15, 263, 12699, 7000, 1475, 8595, 2780, 15509, 10087, 15870, 7631, 14549, 12065, 14619, 3028, 3081

Why are the values not matching? Shouldn't the manual be updated?

For PN23 (notice that the seed given in the manual is big endian, so you need to swap it, and it makes a big change if you do not swap it), my code predicts now for the first values:
3aff 3fd7 2 26e0 a3d 1ca6

which again matches well the manual, table 39, however when I measure I see a different sequence (decimal):

8232, 8189, 14623, 5570, ...

How are these related with data words from the manual ??
