Product Brief
M I C R O T U N E
The MT8872C is an ETS 300 477-
compliant integrated
demodulator and forward error
corrector (FEC) for DVB
terrestrial digital television
receivers and set-top boxes. It
accepts as data baseband or 1st
IF COFDM. The 1st IF sampling
option further decreases system
cost. The 10-bit ADC samples
the incoming signal. The internal
microprocessor locks to the
OFDM signal fully automatically.
The MT8872 can cope with very
severe channel distortions due to
its state-of-the-art channel
estimation unit. The error
correction unit corrects
remaining errors and outputs a
DVB common interface-
compliant MPEG-2 transport
stream.
MONITOR FUNCTIONS
Optionally, data transfer to and
from the internal blocks of the
MT8872P can be provided
directly from the pins (e.g., the
filtered time-domain signal, the
FFT output, interpolated pilots
and the equalized signal after the
channel estimation unit). This
enables real-time monitoring of
channel characteristics for use in
professional applications.
