MT2084

World-Standard Digital Cable Tuner

The MicroTuner™ MT2084 is an advanced, low-power companion tuner to

the MT2082, enabling low cost multi-tuner STBs.

Product Overview

The MicroTuner MT2084 is a single-chip digital cable tuner specifically designed to receive the splitter

output of the MT2082 tuner to enable an advanced, multi-tuner set top box (STB) with a minimal

number of external components. The integrated circuit delivers best-in-class performance for all

world-wide standards of digital cable broadcast. Its high level of on-chip integration enables the

design of a triple tuner set-top box (STB) at a very low cost.

The MT2084 is designed to tune in challenging digital cable environments. The integrated low noise

amplifier (LNA) with automatic gain control (AGC) delivers excellent sensitivity. The ClearTune on-chip

filtering provides for optimal performance in tilted and heavily loaded cable environments.
