The MT2050 is an advanced
single-chip broadband tuner that
has been optimized for high
performance cable modems and
digital cable STBs that require
low composite distortion and
noise under digital cable
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.
