Overview: .. RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND MUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2064 SINGLE-CHIP BROADBAND TUNER
PRODUCT BRIEF The MT2064 is a low-power 3.3V singlechip broadband tuner with an integrated IF variable-gain amplifier. MT2064 Single-Chip Broadband Tuner The MicroTuner™ MT2064 is an advanced, low-power single-chip broadband tuner that has been optimized for high-performance cable modems and embedded multimedia terminal adapter (E-MTA) that require low posite distortion and low noise under digital cable environments. The MT2064 is capable of receiving frequencies in the 48 MHz to 1 GHz range and of converting a selected channel to a standard intermediate frequency (IF) between 30 MHz and 60 MHz. The MT2064’s low phase noise makes it ideal for use in digital applications such as video, voice and high-speed data. 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. In addition, the MT2064 provides excellent in-band flatness as well as very repeatable gain characteristics across the plete reception band. The MT2064’s low-power consumption significantly conserves current and can be effectively used to extend the operation of batterypowered E-MTA.
