MT2121 SINGLE-CHIP
BROADBAND TUNER
PRODUCT BRIEF
The MT2121 has been optimized for
high-performance analog and digital
cable set-top boxes, supporting the 48
MHz to 1 GHz range of the cable
spectrum.
MT2121 Single-Chip
Broadband Tuner
fully integrated single-chip tuner,
with functional blocks specifically
designed to ease implementation of
an OpenCable™ - compliant set-top
box (STB). The MT2121 contains
integrated filter components and
controls that allow for a simple,
alignment-free pre-select filter. This
provides excellent end-to-end
linearity performance for severely
sloped input conditions. The tuner
also has an on-chip amplifier for
Forward Data Channel (FDC)
applications, reducing bill of
materials (BOM) and improving
performance-versus-solutions
based on a directional coupler.
