Description
The STV0362 inherits the functionality of the
STV0361 device and embeds new functionalities
required by the DVB-H standard at the physical
layer side. The STV0362 features the full DVB-T
and DVB-H standards framing structure, channel
coding and modulation. The symbol, timing and
carrier recovery loops are fully digital and sized in
order to match the state-of-the-art RF down-
converter devices.
The STV0362 is compatible with direct
conversion silicon tuners and is featuring two
high-performance differential 12-bit ADC for I and
Q channels. The tuner baseband power is
controlled by a classic AGC loop, and the RF
level is monitored by a dedicated single-ended 8-
bit ADC.
The terrestrial DVB-T network can be subject to
several interference sources which are the
neighboring digital and analog channels, as well
as the in-band analog channels. The STV0362
cancels these interference sources and removes
the effects of impulse noise. The channel
equalization is capable of static and dynamic
echo canceling even in severe urban
environments.
The embedded high-performance algorithms are
enhanced to cope with out-of-guard interval
echoes; specific channel quality monitoring is
available for acquisition and survey.
The specific power handling constraints are
primarily addressed by both technology and clock
rate management. The efficiency of channel
acquisition and re-acquisition also minimizes
power consumption.
The STV0362 relies on the decoder multimedia
processor to manage the MPE-FEC and to
control time slicing while operating in DVB-H
mode.
