RF SILICON AND SUBSYSTEMS SOLUTIONS
FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
MT2064 SINGLE-CHIP
BROADBAND TUNER
PRODUCT BRIEF
The MT2064 is a low-power 3.3V single-
chip 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 composite 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 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 MT2064 provides
excellent in-band flatness as well as
very repeatable gain characteristics
across the complete reception band.
The MT2064’s low-power
consumption significantly conserves
current and can be effectively used
to extend the operation of battery-
powered E-MTA.
The MT2064 can be used in
conjunction with Microtune’s
upstream amplifiers to create a
complete RF front end for bi-
directional cable modem
