MT2060 SINGLE-CHIP

BROADBAND TUNER

PRODUCT BRIEF

The MT2060 is a low-power 3.3V

single-chip broadband tuner with an

integrated IF variable gain amplifier.

MT2060 Single-Chip Broadband Tuner

The MicroTuner™ MT2060 is an

advanced, low-power 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 environments.

The MT2060 is capable of

receiving frequencies in the 48MHz

to 860MHz range and of converting

a selected channel to a standard

intermediate frequency (IF) between

30MHz and 60MHz.

The MT2060’s low close-in phase

noise allows it to be used for both

digital and analog signals including

video, voice and high-speed data.

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.

In addition, the MT2060 provides

excellent in-band flatness as well as

very repeatable gain characteristics

across the complete reception

band. With minor bill of material

(BOM) changes, the MT2060 is

capable of supporting multiple

output standards.

Provisions have been made to

allow the MT2060 tuner to operate in

low power modes. These modes are

selectable using simple software

commands. It reduces current

consumption considerably and can

effectively be used to extend the

operation of battery-powered

applications.
