That's an ATSC device.

If you are using a DVB-T device, you should at least use MXL500x_MODE_DVBT
AFAICS, the zl10353/ce6353 cannot do ATSC ;-)
.delsys = MXL500x_MODE_DVBT

When you don't explicitly know what your hardware does, you shouldn't
try to
apply a tracking filter.
MXL500x_OCTF_OFF, seems to look like a better option for you here, atm
.octf = MXL500x_OCTF_OFF

Crystal frequencies can be 12Mhz, 16Mhz, 20 Mhz or 24 MHz. You need to
identify what your hardware uses.

The IF output depends on your configuration, but for DVB-T using 4.57Mhz as
an initial value looks like a good starting point
.iflo_freq = 4570000
> + .ref_freq = 15,
For the DVB-T device that i use, i do use a reference of 365.6MHz
.ref_freq = 365600000, /* 365.6MHz for the prescribed IF LOF */
> + .rssi_ena = MXL_RSSI_ENABLE,
Till you are very sure about your setup, better alternative is to
disable RSSI,
though you will see a slightly lower signal. But better to see a
slightly lower
signal than to pull out all your hair, while not having a stepping stone
itself.
RSSI should be enabled, when all your frontend is perfect, otherwise
that will
wreak havoc in your setup. Not the best option to start playing with
initially,
especially when you are using with the ZL10353, the demod driver being
sub-optimal.
.rssi_ena = MXL_RSSI_DISABLE
> + .addr = 0x63,
The device can be found at I2C addresses 0x60 and 0x63, You need to find
what's relevant for you.
