MT2068 SINGLE-CHIP
BROADBAND TUNER
PRODUCT BRIEF
The MT2068 is a low-power 3.3 V
single-chip broadband tuner with an
integrated IF variable-gain amplifier.
MT2068 Single-Chip Broadband Tuner
The MicroTuner™ MT2068 is an
advanced, low-power single-chip
broadband tuner that has been
optimized for high-performance
cable modems, DVB-C & DSG
STB’s and embedded DOCSIS
adapters (eDOCSIS) that require low
composite distortion and noise under
digital cable environments.
The MT2068 is capable of
receiving frequencies in the 48 MHz
to 1.0 GHz range and of converting a
selected channel to a standard
intermediate frequency (IF) between
30 MHz and 60 MHz.
The MT2068’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 MT2068 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 MT2068 is capable of
supporting multiple output standards.
The MT2068’s low power
consumption significantly conserves
current and can be effectively used
in battery backed-up EMTA’s,
multi-tuner DVB-C (MPEG) and
DOCSIS (IP Video) STB
applications.
