RF SILICON AND SUBSYSTEMS SOLUTIONS

FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS

The MicroTuner™ MT2121 is a

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)

FEATURES

MT2121 SINGLE-CHIP

•

Dual-conversion architecture for

consistent performance with no

manual alignments

BROADBAND TUNER

PRODUCT BRIEF

Proven performance in dual-

function analog and digital

set-top box designs

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.

Eliminates the need for the 28V

to 33V supplies typically

required by traditional cable

tuners

•

3.3V and 5V serial bus

compatible

Minimal external components;

simple interface to external

filters

applications, reducing bill of

materials (BOM) and improving

performance-versus-solutions based

on a directional coupler.

•

Software shutdown mode

Small 8mm x 8mm 56-lead QFN

Quad Flat package available in

lead-free

APPLICATIONS

All cable-based applications

•

Can be used in conjunction with

Microtune’s upstream amplifiers

to create a complete RF front

end for bi-directional

Advanced analog/digital set-top

boxes including OpenCable
