AUTOMOTIVE TV TUNERS--MT2067 SINGLE-CHIP AUTOMOTIVE BROADBAND TUNER

The MicroTuner MT2067 is an
advanced, single-chip tuner,
optimized for terrestrial television
reception in an automotive
environment.
The tuner is capable of receiving
frequencies in the 44 MHz to 862
MHz range and supports multiple
analog and digital terrestrial
television standards including
DVB-T, DTMB, ATSC and ISDB-T.
A selected channel is downconverted
to a standard
intermediate frequency (IF)
between 30 MHz and 60 MHz.
The MT2067 utilizes an
advanced dual-conversion
architecture that eliminates the
need for external tracking filters.
This is achieved by an integrated
pre-selection filter at the RF input,
low in-band emissions and
outstanding image rejection.
The MT2067 has a high level of
integration to keep the total bill of
materials (BOM) low. Offering a
programmable buffered reference
frequency output the crystal can be
shared with the demodulator or
another MT2067 in order to support
multi-tuner diversity receivers.
In addition, the MT2067
integrates a spur-avoidance
technology, which enables highperformance
in multi-tuner
architectures by preventing
interference between the tuners.
The integrated LNA ensures
excellent system sensitivity and an
innovative architecture enables an
automatic gain control (AGC) range
of more than 100 dB.
The MT2067 is designed for
automotive temperature ranges and
is qualified in accordance with
AEC-Q100.
