MT2063 SINGLE-CHIP
UNIVERSAL TUNER
PRELIMINARY PRODUCT BRIEF
The MT2063 is a low-power 3.3V single-
chip universal tuner for analog and
digital worldwide terrestrial and cable
standards
MT2063 Single-Chip Universal Tuner
The MicroTuner™ MT2063 is an
advanced, low-power single-chip
tuner, optimized for terrestrial and
cable television reception.
The MT2063 is capable of
receiving frequencies in the 48 MHz
to 1002 MHz range. It can convert a
selected channel to a standard
intermediate frequency (IF)
between 30 MHz and 60 MHz.
The MT2063 dual-conversion
architecture yields the desirable
characteristics of traditional
television tuners without 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 MT2063 has a high level of
integration to keep the total Bill of
Materials (BOM) low. It supports
multiple digital terrestrial television
standards including ATSC, DVB-T,
DMB-T and ISDB-T. In addition,
MT2063 supports 256QAM
reception as it is used in world wide
digital cable networks and analog
NTSC, PAL and SECAM signals.
It provides excellent in-band
flatness as well as consistent gain
characteristics across the complete
reception band. The integrated LNA
delivers excellent sensitivity. An
innovative architecture enables an
AGC control range of more than 90
dB. The programmable buffered
reference frequency output enables
crystal sharing with the
demodulator.
