MT2170 SINGLE-CHIP
DOCSIS 3.0 WIDEBAND TUNER
PRODUCT BRIEF
The MT2170 is a low-power, single-chip
DOCSIS 3.0 wideband tuner with an
integrated IF variable gain amplifier.

RF SILICON AND SUBSYSTEMS SOLUTIONS
FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
is an advanced, low-power
single-chip wideband tuner
that has been optimized for
high-performance DOCSIS

and digital cable set-top boxes
that require low composite
distortion and low noise under
digital cable environments.
