REFERENCE DESIGN

RF SILICON AND SUBSYSTEMS SOLUTIONS

FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS

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 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).

The highly-integrated, dual-

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.

ABOUT THE STV0297

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

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.
