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.
MT2060 Single-Chip Broadband Tuner
The MicroTuner™ MT2060 is an
advanced, low-power single-chip
broadband tuner that has been
optimized for high-performance
cable modems and digital cable set-
top 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.
