closest to you is this one with 8MHz bandwidth on the older one I have
without LNA. You might try with AUTO for all, except bandwidth.

T 578000000 8MHz 2/3         NONE        QAM16      8k        1/4       NONE

Haven't find anything special for this one so far on the tda8275a with tda10046a.

An FMD1216ME with tda10046a, not much tested yet, more likely has some
flaw around there on slightly weaker signal.
