FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
M
I C R O T U N E
The MT2060-STV0297-RD is a
cost-optimized, high-performance
Reference Design that eases DVB-C
implementation in cable set-top
boxes. The combination of the
MicroTuner™ MT2060 and the
STMicroelectronics STV0297
demodulator, enhanced by special
adjacent channel filtering and in-
band flatness, meets or exceeds
required DVB-C performance. The
design also features low power
consumption and low component
count.
ABOUT THE STV0297
M2060-STV0297-RD
The STV0297 is a single chip
QAM demodulator that converts an
IF signal to an MPEG-2 datastream.
It is fully compliant with the DVB-C
specification (ITU J83A/C
bitstream) for the transmission of
compressed television, sound and
data signals over cable.
The integrated A/D converter in
the IC allows it to handle 16 to 256
QAM signals and a wide range of
symbol rates without an external
feedback loop or an additional
down-converter stage. The IC
delivers an error-corrected MPEG-2
transport stream with
DVB-C REFERENCE DESIGN
PRODUCT BRIEF
The MT2060-STV0297-RD is an
inexpensive, integrated tuner-
demodulator Reference Design
solution for DVB-C applications.
ABOUT THE MT2060
The MicroTuner™ MT2060 is an
advanced, low-power single-chip
broadband tuner that enables high-
performance RF reception in DVB-C
set-top boxes.
It receives frequencies ranging
from 90 MHz to 862 MHz,
converting the selected channel to a
standard 36.125 MHz intermediate
frequency (IF).
programmable data clock
frequency to an MPEG-decoder.
The STV0297 is fully controlled
using the two-wire serial bus. It
integrates seamlessly with the
MT2060 tuner in this Reference
Design, using a 36.125 MHz IF
frequency.

REFERENCE DESIGN
The highly-integrated, dual-
FEATURES
conversion architecture of the
MT2060 includes on-board band
selection filters. This minimizes
external component count, resulting
in an extremely cost-effective, low-
risk DVB-C design. The MT2060’s
low distortion and low close-in
phase noise makes it an excellent
choice for QAM signal processing
systems. The controlled input
impedance across the entire input
band, and the outstanding image
rejection with low in-band emissions
and spurs makes it the silicon tuner
of choice for such applications.
