The MicroTuner™ MT2063 is an  
APPLICATIONS  
advanced, low-power single-chip  
tuner, optimized for terrestrial and  
cable television reception.  
MT2063 SINGLE-CHIP  
UNIVERSAL TUNER  
Digital terrestrial reception  
Analog and digital PC-TV  
Digital terrestrial set-top boxes  
Portable TV receivers  
PRELIMINARY PRODUCT BRIEF  
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)  
The MT2063 is a low-power 3.3V single-  
chip universal tuner for analog and  
digital worldwide terrestrial and cable  
standards  
TV Plug-in modules  
Multi-standard PCTV receivers  
FEATURES  
between 30 MHz and 60 MHz.  
The MT2063 dual-conversion  
architecture yields the desirable  
characteristics of traditional  
48 MHz to 1002 MHz input  
frequency range  
Supports off-air terrestrial and  
cable reception  
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  
No active external components  
required  
Standard IF output works  
seamlessly with analog and  
digital demodulators  
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  
Low-power 1 W dual-conversion  
architecture with additional  
power saving modes  
MT2063 Single-Chip Universal Tuner  
Integrated RF pre-filter and first  
IF filter  
Single-ended RF input  
Alignment free  
reception as it is used in world wide  
digital cable networks and analog  
NTSC, PAL and SECAM signals.  
It provides excellent in-band  
Integrated power detector for  
closed loop RF AGC  
Integrated IF variable gain  
amplifier for direct connection to  
digital demodulators  
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  
Fully compatible with ATSC,  
DVB-T, DMB-T, ISDB-T, QAM/  
DVB-C, NTSC, PAL, SECAM  
and other terrestrial television  
standards
