frequencies in the 48 MHz to
1 GHz range and converts a
selected channel to a standard
intermediate frequency (IF)
between 30 MHz and 57 MHz.
architecture yields consistent ATSC
A/74 and FCC Digital Cable-Ready
(DCR) compliant performance
without any manual adjustments.
This is achieved via the
combination of Microtune’s
ClearTune technology and an
autonomous automatic gain control
(AGC).

amplifier for Forward Data Channel
(FDC) applications to reduce the
total Bill of Materials (BOM) cost for
a DCR television receiver. It
supports multiple standards
including ATSC, QAM, and NTSC.
In addition, the MT2131 provides
excellent in-band flatness, as well
as consistent gain characteristics
across the complete reception
band for use in digital/analog
televisions, terrestrial set-top boxes
and high-performance PC-TV
applications.
