RF SILICON AND SYSTEMS SOLUTIONS

FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS

The MT2050 is an advanced

single-chip broadband tuner that

has been optimized for high

performance cable modems and

digital cable set-top boxes that

require low composite distortion and

noise under digital cable

MT2050 SINGLE-CHIP

APPLICATIONS

•

Cable modems / voice-

enabled cable modems

Digital set-top boxes (STB)

Home gateways

BROADBAND TUNER

PRODUCT BRIEF

•

The MT2050 is a 5.0V single-chip

broadband tuner with an integrated

IF variable gain amplifier.

FEATURES

environments. The MT2050 includes

all active circuitry required to

implement total RF functionality,

making it the world’s first complete

RF/amplifier silicon front end. It is

capable of receiving frequencies in

the 48 MHz to 860 MHz range and

converting a selected channel to a

standard intermediate frequency

(IF). Supported IF frequencies

include NTSC, PAL, and digital

standards including DOCSIS,

EuroDOCSIS, DVB-C, and ITU J83,

A, B, C.

The MT2050’s low close-in phase

noise allows it to be used for both

digital and analog video signals

including video, high speed data,

and voice. Its dual-conversion

architecture, with no requirement for

tracking filters, yields the desirable

characteristics of traditional cable

television tuners: controlled input

impedance across the entire input

band, low in-band emissions, and

outstanding image rejection.

•

48 MHz to 860 MHz input

frequency range

•

Works seamlessly with all

analog and digital

demodulators

•

Low power dual-conversion

architecture

•

Minimal external components

No manually tunable parts

required

•

Simple interface to external

filters

Integrated IF variable gain

amplifier for direct connection

to digital demodulators

Fully compatible with NTSC,

PAL, SECAM, DAVIC, DVB-C,

DOCSIS 1.0, 1.1 and 2.0,

EuroDOCSIS and other

standards.
