The MT2170 is a low-power, single-chip DOCSIS 3.0 wideband tuner with an integrated IF variable gain amplifier. The MicroTuner MT2170 is optimized for high-performance DOCSIS 3.0-compliant cable modems and digital cable set-top boxes that require low composite distortion and low noise cable environments.

The MT2170 is able to receive frequencies in the 48MHz to 1GHz range and of converting a selected channel to a standard intermediate frequency (IF) between 26MHz and 126MHz. The MT2170’s dual-conversion architecture yields the desirable characteristics of DOCSIS 3.0 broadband functionality.
