MT1384WFC AM/FM
TUNER MODULES
PRODUCT BRIEF
The MT1384WFC is a high-end
AM/FM tuner module with integrated
dynamic selectivity which supports
worldwide AM and FM bands.
MT1384WFC AM/FM Tuner Module
RF SILICON AND SUBSYSTEMS SOLUTIONS
FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
The MT1384WFC AM/FM Tuner
Modules are high-end products
specifically designed to meet the
demanding performance, market, and
pricing targets of automotive
customers. The MT1384WFC AM/FM
Tuners combine the low system
integration effort of a standard “plug
and play” module with outstanding
features and absolute high-end
performance.
These tuner modules offer world
standard functionality by supporting
the various frequency allocations in the
US, Europe, and Asia (including
Japan). The MT1384WFC Tuner
Modules are available with either
horizontal-mount mechanics or
vertical-mount mechanics. Special
custom-designed versions are
available on request.
The AM section of the tuner module
contains an up/down conversion
system with an active prestage and an
audio output. Features such as
excellent sensitivity and very good
large signal performance, together with
the functionality of the implemented
noise blanker, help ensure that the
tuner module produces clear AM
reception - even in critical situations.
The FM section of the module
contains a double down-conversion
system with a selective prefilter circuit
and MPX signal, as well as an RDSMPX signal output. Using appropriate
external signal processing, the stereo
signal and the RDS/RBDS data can be
derived from these outputs. The
dynamic selectivity function
continuously evaluates the current
receiving situation and the current
modulation, and controls the optimum
IF bandwidth automatically. The
dynamic threshold extension
automatically improves the S/N ratio at
low RF input levels. Using these
features, the MT1384WFC Tuner
Modules produce audible signals
where standard tuners produce only
noise and interference.
