M I C R O T U N E M2060-STV0297-RD DVB-C REFERENCE DESIGN PRODUCT BRIEF The MT2060-STV0297-RD is an inexpensive, integrated tunerdemodulator Reference Design solution for DVB-C applications. 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 inband 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 highperformance 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, dualconversion architecture of the MT2060 includes on-board band selection filters. This minimizes external component count, resulting in an extremely cost-effective, lowrisk 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.
