.. M I C R O T U N E™ MT2050 SINGLE-CHIP BROADBAND TUNER CABLE MODEM TUNER AND DIGITAL SET-TOP BOX APPLICATIONS APPLICATIONS - - - Cable modems / voiceenabled cable modems Digital set-top boxes (STB) Home gateways Preliminary and Confidential Features - - 48 MHz to 860 MHz input frequency range Works seamlessly with all analog and digital demodulators Low power dual-conversion architecture Minimal external ponents No manually tunable parts required Simple interface to external filters Integrated IF variable gain amplifier for direct connection to digital demodulators Fully patible with NTSC, PAL, SECAM, DAVIC, DVB-C, DOCSIS 1.0, 1.1 and 2.0, Euro DOCSIS and other standards The MT2050 is an advanced single-chip broadband tuner that has been optimized for high performance cable modems and digital cable STBs that require low posite distortion and noise under digital cable environments. The MT2050 includes all active circuitry required to implement total RF functionality, making it the world’s first plete RF/amplifier silicon front end. It is capable of receiving frequencies in the 48 MHz to 860 MHz range and converting a selected channel to a standard intermediate frequency (IF). Supported IF frequencies include NTSC, PAL, and digital standards including DOCSIS, Euro DOCSIS, DVB-C, and ITU J83, A, B, C. The MT2050’s low close-in phase noise allows it to be used for both digital and analog video signals including video, high speed data, and voice. Its dualconversion architecture, with no requirement for tracking filters, yields the desirable characteristics of traditional cable television tuners: controlled input impedance across the entire input band, low in-band emissions, and outstanding image rejection.
