MT2062 SINGLE-CHIP

BROADBAND TUNER

PRODUCT BRIEF

The MT2062 is a low-power 3.3 V

single-chip broadband tuner with

integrated loop-through for all-digital

set-top boxes.

MT2062 Single-Chip Broadband Tuner

advanced, low-power single-chip

broadband tuner, with loop-through,

optimized for Digital Video

Broadcast via Cable (DVB-C) set-

top boxes.

receiving frequencies in the 48 MHz

to 862 MHz range and of converting

a selected channel to a standard

intermediate frequency (IF)

between 30 MHz and 60 MHz.

architecture, without any need for

tracking filters, yields the desirable

characteristics of traditional cable

television tuners. This is achieved

by careful control of the input

impedance across the entire input

band, low in-band emissions, and

outstanding image rejection.

(BOM) cost of a digital set-top box

low, the MT2062 has an integrated

on-chip loop-through function. In

addition, the MT2062 provides

excellent in-band flatness as well as

very repeatable gain characteristics

across the complete reception

band.
