Hi,
I do not know how to confirm if the values are all correct.
Unfortunately, I do not have the measurement transmitter at the moment,
so I can only say that with a converted signal, our own CU1216-based
device runs.
The parameters we use (taken from data sheet and/or demo software) are:
LTHR: 0x78, 0x6e, 0x4b, 0x37, 0x2d, 0x23
MSETH: 0x8c, 0x6e, 0x4b, 0x37, 0x2d, 0x23
all the others, except for AGCREF that I had to adjust to 110 (0x6E) for
QAM256, are the same - but I do not think that LOCKTHR and MSETH could
make such a big difference here.
I tested here (QAM128, Tampere Finland) using the exact same
tda10021-i2c-register values windows driver is using (AGCREF 0x50, LTHR
0x2d, MSETH 0x2d, PWMREF 0x80, checked with saa7146dump). It did not
affect the distortions. I think the problem isn't in those.
