M I C R O T U N E ® MT2060 SINGLE-CHIP BROADBAND TUNER PRODUCT BRIEF The MT2060 is a low-power 3.3V single-chip broadband tuner with an integrated IF variable gain amplifier. The MicroTuner™ MT2060 is an advanced, low-power single-chip broadband tuner that has been optimized for high-performance cable modems and digital cable settop boxes that require low composite distortion and noise under digital cable environments. The MT2060 is capable of receiving frequencies in the 48MHz to 860MHz range and of converting a selected channel to a standard intermediate frequency (IF) between 30MHz and 60MHz. The MT2060’s low close-in phase noise allows it to be used for both digital and analog signals including video, voice and high-speed data. Its dual-conversion 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. In addition, the MT2060 provides excellent in-band flatness as well as very repeatable gain characteristics across the complete reception band. With minor bill of material (BOM) changes, the MT2060 is capable of supporting multiple output standards. Provisions have been made to allow the MT2060 tuner to operate in low power modes. These modes are selectable using simple software commands. It reduces current consumption considerably and can effectively be used to extend the operation of battery-powered applications.
