MT2022 SINGLE-CHIP MoCA™-COMPATIBLE BROADBAND TUNER

The MicroTuner MT2022 is an advanced single-chip broadband tuner that has been optimized for

high-performance analog and digital cable set-top boxes that require low composite distortion and noise under fully loaded (174 channels) cable environments. It is capable of receiving frequencies in the 48 MHz to 1.1 GHz range and of converting a selected channel to an intermediate frequency (IF).

FEATURES

• The MT2022 features many advantages including:

• On-chip amplifier for Forward Data Channel (FDC), which reduces bill of materials (BOM) cost while improving performance vs. solutions using a directional coupler.

• 1.1 GHz bandwidth

• Ease of multi-tuner front-end implementations

• Proven performance in dual function digital STB designs

• Eliminates the need for the 28V to 33V supplies typically required by traditional tuners

• 3.3V and 5V serial bus compatible

• Minimal external components

• No manually tuned parts required

• Simple interface to external filters

• Software shutdown mode

• Intermediate frequency (IF) output fully compatible with demodulators for DSG, DAVIC, DVB-C, DOCSIS™, EuroDOCSIS™, and other standards

• Can be used in conjunction with Microtune’s upstream amplifiers to create a complete RF front end for bidirectional STB applications

APPLICATIONS

• DSG in cable STBs

• All-digital cable STBs
