MT2064 SINGLE-CHIP

BROADBAND TUNER

PRODUCT BRIEF

The MT2064 is a low-power 3.3V single-

chip broadband tuner with an integrated

IF variable-gain amplifier.

MT2064 Single-Chip Broadband Tuner

advanced, low-power single-chip

broadband tuner that has been

optimized for high-performance

cable modems and embedded

multimedia terminal adapter (E-MTA)

that require low composite distortion

and low noise under digital cable

environments.

receiving frequencies in the 48 MHz

to 1 GHz range and of converting a

selected channel to a standard

intermediate frequency (IF) between

30 MHz and 60 MHz.

makes it ideal for use in digital

applications such as 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.

excellent in-band flatness as well as

very repeatable gain characteristics

across the complete reception band.

consumption significantly conserves

current and can be effectively used

to extend the operation of battery-

powered E-MTA.

conjunction with Microtune’s

upstream amplifiers to create a

complete RF front end for bi-

directional cable modem
