> Regarding stb6100 doc the tuning procedure should be:
> 1. Disable PLL (LPEN_LPEN)
> 2. Set-up the tuner
> 3. Start PLL
> 4. Start VCO search
> 5. Wait for 5 ms
> 6. Disable VCO search, turn off VCO search clock and disable LPF BW clock
> The steps 1-5 should be done in 5 steps (not less) and as I remeber I've got
> better result when inserting small delay between steps 1 and 2 and the delay
> from step 5 was set to 10ms. In stb6100.c are steps 1 and 2 done together
> within 1 write to stb6100 registers and this seems to be not optimal for some
that's why TT3200 owners have to try both patches together - from you and from Alex Betis ?
is it correct ?
